I haven’t lived in the US for a few decades now, so I might definitely be off for some!

American tipping culture is so arbitrary though. You tip your taxi driver but not your bus driver. You tip at a coffee shop but not at a fast food shop. Your hairdresser gets a tip but not the people looking after your children.

I’m a foreigner and the last time I was in Germany it ended up being a nightmare of delays and me running across stations desperately trying to get out of Germany.
