Not comparable at all.
At Applebee's, you have to practically beg the waiters to come to your table and refill the drinks.
At a higher end restaurant(hell, even cheap places like IHOP and Olive Garden are considered higher end than Applebee's), no begging is needed to refill your drinks. The waiter comes by and ask you if you need anything before you finish your drink, or sometimes serves you two cups of your drink the 1st go round without you asking for it.
It's exactly the same.
At the higher end restaurant I will be paying a considerably higher price for the food in the first place.
The food will be better, the tables will be nicer, the crockery will be nicer, the cutlery will be better...
All of which is paid for in the price.
The tipping nonsense is just that - nonsense.
