My boss complains about everything

I work for an entrepreneur. She owns a few businesses and plays the good ole stock market.

I realized early on that she's incapable of working with OR for others and that's why she works for herself. She loves telling people what to do, how to do it, when to do it and exactly what will happen if you don't. Warm comforting feelings must race through her veins when she bosses people around.

I also realized that she LOVES conflict. She feeds off of it. At a moment's notice or without notice at all, she is ready, prepared and already firing angry verbal darts at her employees without any thought towards professionalism, office etiquette or protocol.

She would say that everyone works for her because they aren't smart enough to work for themselves.

She's also a complainer. I had to drive my boss somewhere recently. "Had to". My boss owns about 6 vehicles, but somehow she wanted me to drive her somewhere. I drove. My vehicle is a little older, yeah yeah, the a/c doesn't work but the car drives and I'm very happy to have it.

We had the windows rolled down enjoying the air. My boss began bitching about the Mexicans in the car next to us. "I can smell them" she said. She said other things which I wont share.

Another vehicle drove by us, one older than mine. My boss complained about the smell of that car- the gasoline smell, the emissions, the people driving it. I just sat there in silence not really caring what level of bitterness my boss was living in.

Then she said I needed to drive past the smelly car so she didn't get nauseous and vomit. I should have asked her if she wanted some Avian Water too or a warmed face cloth. She complains about everything.

Why couldn't we have taken one of her luxury cars on the errand?
