Robin: I think the waiter (forget) HAS FORGOTTEN us. We (wait) HAVE BEEN WAITING here for over half an hour and nobody (take) HAS TAKEN our order yet.

Michele: I think you're right. He (walk) HAS WALKED by us at least twenty times. He probably thinks we (order, already) HAVE ALREADY ORDERED.

Robin: Look at that couple over there, they (be, only) HAVE ONLY BEEN here for five or ten minutes and they already have their food.

Michele: He must realize we (order, not) HAVE NOT ORDERED yet! We (sit) HAVE BEEN SITTING here for over half an hour staring at him.

Robin: I don't know if he (notice, even) HAS EVEN NOTICED us. He (run) HAS BEEN RUNNING from table to table taking orders and serving food.

Michele: That's true, and he (look, not) HAS NOT LOOKED in our direction once.
