Robin: I think the waiter ... \(forget\) us. We  ... \(wait\)  here for over half an hour and nobody ... \(take\)  our order yet.
Michele: I think you're right. He  ... \(walk\)  by us at least twenty times. He probably thinks we  ... \(order, already\).
Robin: Look at that couple over there, they  ... \(be, only\)  here for five or ten minutes and they already have their food.
Michele: He must realize we  ... \(order, not\)  yet! We  ... \(sit\)  here for over half an hour staring at him.
Robin: I don't know if he  ... \(notice, even\)  us. He  ... \(run\)  from table to table taking orders and serving food.
Michele: That's true, and he  ... \(look, not\)  in our direction once.
Robin: Look, he is coming!
Waiter: Good evening Sir, Madam. ... \(order\) yet?
