Ya fuck that place. Tell me the price of what I'm buying or we don't have an agreement for me to pay.

I don't want a goddamn algebra equation to guess what my bill will be either. I will assume anything extra is the gratuity, and 100% optional (up to me). There isn't going to be any extra gratuity when the person I ordered from hands me a surprise bill >20% than what I ordered.

Nope.
