The store I get my mostly fresh groceries from has its core cashiers capable of reducing a line of twelve people in mere moments (due to their superior change calculating, and register button pressing skills) and the guys who fill in when it’s slow. I think there was a very new guy helping me out because he said “thank you” in inordinate number of times and after taking a look at the fish and veggies I bought asked if I wanted chopsticks and soy sauce with that. It just struck me as a tremendously odd thing to ask even if he was just trying to be nice.
