I struggled with this last night... I don't know why, maybe I'm cost concious in this economy.

There was a delivery charge added to the price of the meal and 22% gratuity and then tax and everything.
There is a line for additional tip....

Who gets what? does the server get any of that? At a restaurant I tip 18-20% everytime... here they charged 22% automatically.

Should I be adding on top of that? I have to say that I always do, but yesterday I read through it and struggled a bit.

thoughts?
