MadridMan- I think you’re right and its more cultural differences. When I say super polite, it was basically stopping my conversation with companions and acknowledging servers by saying ‘thanks’, etc. when they bought stuff to the table. It wasn’t over the top fake or inauthentic but just remembering manners even when I was engaged in a great conversation with people at the table. Fwiw—I definitely don’t mind people being themselves, but when I’m paying for a service (here or aboard) I would like a soda served without literally slamming the glasses down on the table and a bad attitude.

As for tipping a housekeeper/maid, I think Booklady is on the mark since tipping isn’t the norm. I’ve never heard of praise not being appreciated worldwide. (especially in front of the boss)
