I traveled to Miami for the first time last week, and every nice restaurant I went to had included a mandatory 18% gratuity to the bill. (This was dinner for 2, not a large party.)
First off, I don't really care, the service was fine, and I normally tip 20%, so it's not like I wouldn't have paid it.
But...It struck me as REALLY weird. No other city does this. I had to actually ask the waiter that I interpreted the bill correctly.
So, my question is, what is it about Miami that you include an gratuity on a normal tab?
