> As an American that has travelled overseas years ago, I understand that others in the world could do without us visiting. They just want to have their normal day to day without an American speaking American English and commenting on things like an American and tipping wait staff, asking for ice, expecting things that aren’t provided, generally acting more entitled, etc.

It’s perfectly possible to visit and be aware of local sensibilities. Plenty of Americans manage it and are perfectly charming visitors.

You don’t have to adopt all of culture’s behaviours to not be obnoxious
