The last cab I was in, the driver was asking my girlfriend how to get where we were going (Chinatown in LA from downtown...not exactly challenging), which she didn't know because she doesn't drive. He was rude to us both the entire time, and then when we got out, (even after she left him a reasonable tip), he called her a "fcking btch" and sped away. We tried complaining to the cab company a few times but nothing came of it. I've never had an issue even remotely close to that in Uber/Lyft, but have had more unpleasant than pleasant experiences in taxis all over the country.
