There are many reasons to avoid certain groups as customers. Violence, false accusations, unreasonable demands, etc.
Then there is the question of payment and gratuities. A large percentage of women and certain ethnic groups are notoriously averse to tipping, even those that work in the service industry and rely on tips themselves.
You as a driver take in a black man from or near a bad neighborhood and you can get robbed or killed, or the fee not paid. Too much risk involved. Women meanwhile, don’t tip as well as men. Blacks often don’t tip at all.
Well, I’m a woman; and my Daddy taught me to tip at least 20% for everything; and I always do.
I wouldn’t use Uber or Lyft. I like the old-fashioned cab companies with full-time, experienced drivers. I’m not comfortable with just *anybody*, who decides to get a few bucks doing this a few hours per week, driving me around.
Women are crap tippers. Blacks are worse.
Certain predictable stereotypes did not come into existence for no good reasons.
