I sketch a tick mark in the air with my finger to indicate to the waitron unit that I want my bill.


I, on the other hand, being the classy dame that i am, mime signing the bill. The implication being (in the days before credit card) that I had a "house account" which allowed me to sign the bill and be billed privately.
Please don't call me a snob before you look the word up in the OED!
