Some people are just unhappy that they don't even know what they're doing. You can just go to the Manager and express your concerns.
I haven't found that to be the case.
I mean, do you have an attitude? I've seen that be the case most times. If you have a problem, of course bring it up. But it doesn't have to be in a rude way. (Not saying you do, just people in general) especially during busy hours and stuff. But either way, it should be handled nicer on both ends.
