It's often a matter of wording, the way you say things. You can say the same thing in a polite friendly manner or an accusatory manner. Some people don't know the difference between "Please leave positive feedback if you're satisfied with the transaction" versus "Give feedback when the transaction is finished, buddy." You can say the same thing, have the same rule, but one is worded a way that offends and one that doesn't.

I'm a volunteer and have told my bosses that I don't particularly care what task they give me, so long as the say "Please" and "Thank you." It's really that easy with me. I had a hard driving boss, but liked working for her because she always politely asked me if I wanted to do a task and thanked me when it was done. If no one said please or thank you, or something with similar sentiments, I'd have quite a long time ago.
