HOW did he treat others better then you?

when you yell at a manager..that is a sure way to get unemployed fast. you applied to be a manager....this shows me you are not ready to be in that position yet.

who cares why he is in a bad mood. maybe he & his wife had a fight, the dog pooped in the house, check engine light went on in the car, maybe he didn't think he had to call anyone in but was told to, what ever the reason....it's his call. by you stressing over it it makes you look worse. come to work. do your job. go home. no drama. none. period.
