So I've been thinking about this a lot recently: do you tip the carhop at Sonic (or any other drive-in restaurant)? Realistically, all they're doing is giving you your food -- they don't check up on you or refill your drinks. Sometimes, I'll pay with cash and leave the change for the carhop. But today, I paid with my debit card -- so after debating in my mind for a few moments, I decided to give the carhop a $1 tip. So, any thoughts on this? Anyone ever work at Sonic as a carhop?
