I get people that write checks out in the line, it's no big deal. Sure it takes longer but maybe this person can't handle carrying a little card that can easily be dropped or stolen. With a Check, usually the person MUST present a Drivers License. With a credit card, all you do is Swipe, enter pin if it's debit, and just sign. Rarely ever do stores actually ask for my card and look at the back where I wrote "ASK FOR ID". Writing Checks doesn't take that long. All you have to do, is write the check out in advance, all you have to fill in is how much to pay. That's what I do. Usually I'm done writing the check and the employees aren't done with bagging my clothing. So it's the same as waiting for a person to bag.
I have a friend who's credit card was stolen and she had "ASK FOR ID" on the back of it. She hadn't canceled it to see how far it would go. The person who stole the credit card was able to go to 13 stores without being caught until the 14th store asked for ID and contacted officials. She now uses checks.
I know you can easily cancel a CC but then it takes a while for you to get the new CC, so I don't want to hear that.
