The post above.... yeah, if you go to a restaurant, the waiter/waitress asks you what you want to drink. I don't think I've never heard one specifically state pop/soda/coke, because there are other things to drink besides that. (Iced tea, water, coffee, etc). So not really sure what the point is there.
The point was that people who use pop do so as often as possible. People who use soda... rarely actually do.
A better real world example is if someone sends you to the grocery store, asking you to bring home some variety of carbonated beverage. What do they ask you to pick up. Say in their head they were thinking of rootbeer, or ginger ale, or maybe cola, they don't care, just some carbonated beverage:
Can you pick up some pop at the store on the way home?
Can you pick up some soda at the store on the way home?
Can you pick up some drink at the store on the way home?
Can you pick up some coke at the store on the way home?
Now, if someone asked me to pick up some "drink", I'd be like wtf are you talking about? And totally wouldn't think they were specifically asking to get a carbonated beverage. Around here, most people would ask me to pick up some pop on the way home. I would understand that to mean any carbonated beverage. Soda would also make sense to me.
Ugh. Now you're asking a question based on a loaded and wrong premise just like the survey the map was based on. The reason "drink" sounds funny in your scenario is because you deliberately got the plurality wrong.
Question for the person driving home: "Pick up some drinks on the way home." Reply: Diet or regular?" Note: Request did not need to say soda/pop because the request didn't say juice, milk, beer, tea, etc. You can assume that the person would have been specific if they weren't talking about flavored drinks and if they wanted to be that specific about a flavored drink then they would have named the brand/flavor. It's obvious what they want.
Question by the person in the drive thru: "What drink would you like with that?" "Answer: actually, I'll substitute a milk shake."
Question for the person getting gas at a gas station/convenience store: "I'm thirsty. Could you get me something to drink?" Reply: "Sure. Can, bottle, or fountain drink?"
Question for the person passing the vending machine: "Hey, man. Grab me a drink from the Coke machine on your way back from the office, will ya?" Reply: "OK, but last time I passed it they only had diet."
You'll note that "soda" was not used in place of "pop" even once. Calling a vending machine a "Coke machine" is not the same as calling any soda a "Coke," but it could be another explanation for that map being completely wrong. Some people sometimes call a Pepsi machine a "Coke machine" for the same reason you might call an AMP connector a Molex connector: the brand is too closely associated with the function. Yes, to many people, all tissues are Kleenexes, all cotton swabs are Q-tips, all adhesive bandages are Band-Aides, all hook & loop fasteners are Velcro, and all petroleum jelly is Vaseline, but very few people call all sodas "Coke" even if measurably more associate the world's number one brand with all beverage vending machines.
If someone asked me to pick up some coke on the way home - I'd specifically pick up Coke brand. Do people in the south really say "pick up some coke" when they are asking about getting root beer, ginger ale, etc?
No. Some idiots do and it may be higher in the South, but I've never met one and it is not prevalent in any region no matter how much the map implies it is. If you order Coke at a Pepsi establishment, it is interpreted as the flavor (cola) in any region. The only place I regularly see the word Coke used as a substitute for non-cola flavors is when referencing the vending machine, as shown above.
Your entire argument is wrong. You seem to think that the infographic asks the question, "What do you call all drinks?" And you seem to think the answer is "drink." That's not even the question.
Nope. I'm saying that the question is stupidly assuming that the question applies equally to the different regions. It doesn't. in almost every single place someone would use "pop," a so-called "soda" person would use "drink." The poll simply tested their vocabulary to find out what they would use when being extra specific for responding to polls or in conversations like these. Get it? There is almost no reason to ever specify "soda" or "pop." The regions that don't use "pop" DON'T SPECIFY outside of silly conversations like these. It's almost never needed. Pretending that we use it equivalently to make an infographic of incomparable results just because it is the equivalent in our vocabulary is exactly what made the premise and entire result wrong.
Soda/Pop/Coke is a segment of drink, and the question (I can't believe I have to spell this out) is, "What do you call soda/pop/coke/carbonated beverages?"
I can't believe I'm having to spell this out for you when I already said it: WE CALL THEM "DRINKS." We only call them "sodas" when we need to distinguish, which is almost NEVER! Can you honestly say that people who use "pop" almost never use it?! No. That difference in use MEANS SOMETHING!
Why would "drink" even be an option? Do you have a drink of "drink" when you have a Pepsi? Do you say, "Hey pick me up some "drink" at the store" and expect them to come back with Dr. Pepper or Cherry Coke?
Are you deliberately leaving out the s in drinks to sound like an idiot? "Drink" is a real word with an English definition that conforms to English rules. It isn't the name of some segment of drinks. You can ask for sodas or pops with an s when you want to make sure someone doesn't just buy one, so don't pretend that you have to leave the s off of those too unless you want to sound like an idiot. I'm not saying "drink" should be the option. I'm saying the poll question was irrelevant to the real question and the real question make results incomparable. I'm saying that "drink" is the answer to the REAL question of "what do we actually call pop in places where we don't call it pop?" I'm saying the poll was dumb (assuming it's source was really a poll) and the answers are incomparable and the infographic based on them was meaningless. It should not have existed with or without a "drink" option.
You see?! Your and it's assumptions are exactly what I am talking about! First, you assume that we need to reference that segment of all drinks, when outside of discussions like this: WE DON'T! That was my entire point. Almost anywhere you weirdos use "pop," the distinguishment from other drinks was entirely unnecessary. You're damn right I'll have a SIP of my Pepsi (see what I did there?). You're damn right that we'll ask each other to pick up some drinks at the store and expect flavored drinks if I didn't specify. Do you think I mean milk? Beer? Tea? Unlike "pop" or "soda," specifying those drink types is equivalent to specifying a flavor like Dr. Pepper or Cherry Coke. If no drink type is specified, then you probably mean the kind of drink that can be flavored variously and is often sweetened and carbonated, which generally fits soda/pop and would never be confused with various flavors of alcohol or something. It's also generic enough to include various flavors of cold tea, which is often intentional. Iced tea holds a nearly equivalent position in most places. If you asked someone for drinks and they came out with a selection of sodas, energy drinks, and Snapple/Arizona, then they did exactly what you asked. If you wanted 7-Up or Diet Coke, you should've said so. Same goes if you were asking for "pop."
