A few years ago I called a restaurant to make reservations and this is the conversation that ensued.
Restaurant: Thanks for calling La Ristorante Authentico (not its real name).
Me: I'd like to make a reservation for six-fifteen, please.
Restaurant: I'm sorry, we don't take reservations here, we do call-ahead seating.
Me: What's that?
Restaurant: If you can be here in 10 to 20 minutes you call ahead and we seat you when you get here.
Me: Okay, I'd like to be seated at six-fifteen.
Restaurant: I'm sorry, it's only a quarter to six now. You'll have to call back at six o'clock.
Me: Well, can I have you write me in now for six?
Restaurant: Sure, that was for six people?
Me: No, six o'clock. Ten people.
Restaurant: Ten people? Oh, we can't possibly be ready for ten people in fifteen minutes.
Me: Okay, can you set us up for six-fifteen?
Restaurant: Sure.
When we arrived we weren't seated until 6:30. Several of our party ordered lasagna. The waitress returned after placing our order to tell us they were out of lasagna. After
selecting alternates and waiting a while for them to arrive, we were
told that there was lasagna after all and we could change our orders. It's a good thing we didn't, our food took an hour to arrive. Probably because they didn't start the order until after they offered us the newly-found lasagna. I always wondered where they found it.
