What's your biggest turn-off when getting to know someone?

Mine is when I discover she is obsessed with wealth. When she wants to buy expensive stuff, or want to have expensive clothing, or wants to work long days, just to have more money, I have to end it. I can't be with a girl who will spend money on some expensive car, while people are dying because they can't afford food or medical treatment. I can't be with a girl who thinks her main aim in life should be to command as many cubicle slaves as possible either.
