#6 – He Is Rude
Being polite is one of the most necessary attributes of a person. He doesn’t have to be acting like a lord of course, but some basic knowledge of proper behavior is a must. If he tends to yell at the cashier lady for some petty reason or is commanding the waiters around as if they were his slaves, you should send him off as soon as you see such behavior. It won’t be long before he starts treating you the same way. So don’t let it come to that.
