I've done a search as I know tipping is asked a lot.
I didn't realise that workers are taxed on their tips - that is insane. I'm glad I read that as I'm from Australia where people get proper wages and tipping is something to do if people do an excellent job. I am glad I read about the culture in the US before I went.
I think I'm fine on cab tips and restaurant tips from searching but i have a question about the doorman.
At my hotel there is a doorman, do I tip him when I first arrive when he opens the door or do I tip him if he gets me a cab or tells me directions etc?
How do people do it in a good way which isn't patronising?
Chambermaids - I know the amount but do I leave the money on the bed or with a little note?
