The mental maths at the end of every meal used to genuinely stress me too. What helped was just asking a local friend point-blank 'what do YOU actually leave?' โ the real answer was much lower and simpler than my anxious over-tipping.
Restaurants, taxis, the hairdresser, the delivery person โ back home I had clear rules, and here I genuinely never know if I'm insulting someone or being taken for a fool. I've started over-tipping out of anxiety, which isn't sustainable. How did you all figure out the local norm without a dozen awkward moments first?
