Ok, we discussed tipping the oil change guy, but what about curbside carryout at Applebee's, or when you pick up at the local pizza joint, or you pick up Chinese for dinner? I always struggle with that. Usually I tip just under 20% on sit down (I round, usually down, to the nearest dollar from 20%), but on carry out from a sit down restaurant, I usually give half of that. Sometimes not. Pizza? Hit or miss on tipping for me. I feel more inclined to tip when they carry it out to the car for me with curbside carry out.
