history: I am annoyed by people who won't return their grocery carts, and just leave them in the parking lot! Okay_comma_ a silly pet peeve but one nonetheless -- when people just leave their grocery carts willy-nilly in the parking lot. No consideration for others or the people who work at the store!
current: Absolutely I agree I always try to not even bring cart unless I have too many too carry.
next: Me too. And I will always make sure to at *least* put it in one of those cart corrals, if not walk it back up to the store. Hey -- extra exercise ;-)
