Coming from the other side of the world where tipping is neither the norm nor expected, the thing that I would find useful if a simple list of who you are supposed to tip and how much when we are in the US. I understand cruise tipping, but it's off the ship that has me confused.
I realised while reading this thread that I should have given extra to the shuttle van driver who picked me up at my hotel and took me to the airport when I was in the US recently?
I agree that you should follow local customs with tipping, but it's a bit difficult to do this if you don't know the rules. Can anyone help?
