Yes, I've seen Reservoir Dogs too. Without engaging the extremely shopworn discussion about how much tipping is appropriate, the fact remains that if you choose, you can tip a waiter nothing. It may be a dick move, but you can do it. You can't "tip" an Uber driver nothing. It doesn't matter how bad your service was. It doesn't matter how much you don't care about being labeled a dick. You just can't do it. Because the Uber thing is not, in fact, a tip.
