I’m from Australia, where we don’t tip; and yes; you have to in America. It’s likely that the person serving you needs tips to survive, so think of it as money for them directly. (even tho in most cases I don’t think they get 100%?) I make a point of not tipping at home because people should get paid a living wage without having to rely on tips. I say you’d be the asshole because customer service employees in USA need that extra money to make ends meet.
Yeah likewise and this has been pretty great.
