At the restaurant

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. __________ you __________ (order) yet?
