I am actually a driver myself. I agreed to all the rates and how much I get paid when I signed up, so why are other drivers so upset for not getting tips? Is this a matter of expectation?
Why do Uber and Lyft drivers become so angry when riders don't tip?
I don't get angry about it but it is sometimes annoying.
I think it is mostly because people do usually tip taxi drivers but Uber has trained riders not to tip rideshare drivers, first by telling them "the tip is included" then by telling them "there's no need to tip" after they were sued. People didn't just decide overnight to stop tipping drivers. Uber intentionally discouraged tipping to keep riders spending more of their travel budget on fares & less on tips.
I also find it annoying when riders promise a tip then don't follow through. But in this case I am more annoyed by the dishonesty than the not tipping itself.
