Why not complain about them? Look at the incident with the whining procrastinator. My co-worker refused to wait on her. I should add that my coworker is ready to quit and has cut her days down to two. She needs the money because, like me, she's an adjunct faculty member. However, the sheer boredom of the work . . . having to deal with people who are stupid, rude and arrogant . . .having to work under a woman on wheels who is also a hypocrite (one day I moved 60 cases of wine . . . I'm 5'3", 118 pounds and she's at least 5'9" and perhaps 180 or more. . . while she moaned about her back . . . gimme a break).
People think they have a license to be nasty when they are customers. They love to say that the customer is always right. I have seen it time and time again so I have always bent over backwards to be nice to store clerks.
I have heard customers tell store clerks they are ugly . . . one such clerk was a 28 year old natural blonde who wore a size 4 who is extremely attractive.
In fact, I don't find much good and gentle "golden rule" behavior out there.
Now, I have a following at the wine store . . . but most of the clerks do. I have made friends among the customers . . . and I have had to make certain that I cooled the ardor of a couple of men.
You certainly do not believe in turning the other cheek. Why should I? It would be less than honest.
