End of the trip I go pay, and he's sad that I want to pay with a credit card. Then the tip meter only has 20% or other. I hit other with a much lower tip. He cancels the transaction from the front, and says that the ride is actually 150 not 100, and that's why I need to tip. So I say fine and end up tipping him the 20% at 100.
But seriously isn't a tip like a bonus!? Why are we all required to give 20% tips even when the service sucks?
Next time I'll just uber.
