I don't agree with the argument that passengers should tip because Uber isn't paying their drivers enough. That sounds like welfare for Uber. If the pay sucks, Uber should have trouble recruiting drivers.
I really hate tipping culture in America. In Germany, servers are surprised if you give them anything more thana euro. I have friends who visit from non tipping cultures who ask "Why isn't it just included in the price!" I agree with the author. Tipping is out of hand. Charge more for food, clearly state it on the menu/check, remove the tip black on the receipt and pay people a decent wage!
It's the worst when I'm picking up takeout from a restaurant that also has tables. Like, am I supposed to tip in this scenario? Do I have to go into "other" to tip less than 20% for being handed a brown bag?
