I once had an uber driver call me up to ask where I was going. He was in an airport waiting queue and didn’t want to leave it if I wasn’t going to anywhere he didn’t want to go. I was going too far for his preference. In his poor english he demanded I cancel the ride instead of him doing it after he accepted. It is a violation of uber rules to ask before pickup what the destination and refuse it and it is also a violation to request that I cancel (It was late and I wanted to get on to another driver anyway).
I reported him to Uber and only got a stupid weak form letter saying they are working to educate their new drivers about the rules. There was no mention of his getting fired for it.
I used Lyft and with Lyft one always puts I the destination address before a driver is assigned.
