Goq: I find your post very interesting, as I’ve never worked in a supermarket, but wondered about certain things. In particular:
1. Is it easier for the staff if I pay by cash, or by CC?
2. Is it common in the industry to get bonuses for customer compliments?
3. It’s possible that the smokers are embarrassed to ask for smokes, or maybe not having had one in a while makes them grumpy, or they smoke to overcome their depression.
