That one really good measure of someones character is how a person treats someone who they think is lower on the social order than they are... I.E. say how a CEO treats a waiter or a bank teller..
Friday, I had a person prove how low their character really is. First he trashed my employee, then when I stepped in, as a manager, he attempted to trash me. When I asked him to leave, he suggested that he would speak to my supervisor. He was dismissive and insulting and downright rude and referred to both of us as "minimum wage drones". I explained that I was also the owner of the business, and he could complain all he wished, but he was still leaving.
His demeanor changed entirely. Having had no idea that I was the owner, he assumed he could rant and rave with impunity. When he realized he couldn't slam someone "lower" than him, he became all servile and such.
Too late, brother, go find somewhere else.
