When I'm confused, I kill no braincells, I tip 10%, so I just move the decimal and done. If I'm annoyed, I tip $0. I think in the US most people don't have a frame of reference of what it's like to not have this social pressure to tip. You feel much better when you tip without being forced. Also, as a foreigner, American workers and businesses have no idea how vexing it is for a tourist to land, have a budget and realize that they're 30% short because of tipping everything from expensive Uber rides to hotels and luxury spas. This is basically the US tourist tax, even though all our money is going to already stay there. There a probably quite a few uber drivers that hate me now, because they try to give me the all star ride, have a conversation, hear all my compliments (bc they keep nagging if everything is to my liking, if I want music or the AC adjusted), and then get zero tip. I absolutely do not feel an ounce of remorse. Why? Because I have also come to understand that they're not really providing quality service because they care. They're all gaming the system and manipulating customers. here's an example: I once needed an Uber from NJ to NYC, urgently. One quickly responded, arrived, started chatting and being friendly, started the trip and after I loaded all my stuff into the car, she looked at the destination and told me they would not drive to NYC, that I should get out. She left and did not cancel the trip. I had to contact Uber to get refunded. My point is, the 5 star friendliness ended the second I stopped being profitable for her, and at that point I stopped mattering. So yeah, smile away, no tips unless I am wowed beyond my expectations.
