Who on earth is carrying cash? I'll give one stars to any driver asking for tips in cash.

I think you are still in minority about not carrying cash. Also the drivers rate you as well. Pretty sure you will be the one kicked off for low rating before the drivers.

I suspect the risk of a paying customer getting kicked off the system is far lower than a driver who provides an off-brand experience.

I think that's unfair. I won't start carrying cash. I guess I'll switch to whoever lets me tip through the app.
