I did around 450+ trips in one and half months. Suburbs people are friendly and usually give tips then city. I never ever received any tip from city pax on Uber. Max tip I got $15 tip on suburb ride to lake in the hills at 11.30 pm on friday night. City driving is stressful and all shorter trips then suburbs. Plus city pax, mostly are not nice as suburb pax. Is it me or anyone else has similar experience? I got tips from City pax on Lyft but never on Uber.
