Everyone wants a tip now, so what was previously an annoying but understandable practice for very service-oriented roles (where the service could dramatically change outcomes) morphed into an effective 20% sales tax on every human you interact with. I tip people who handle my exposed food and luggage. Nobody else. Given the anecdotes that few people tip for food delivery, I would be curious how much delivery costs vs eating out when factoring the 20% social tax.
