223.
W: Waiter! I'd like to speak to the manager please... immediately if possible.
M: Is anything wrong, Madam?
W: I'm afraid there is. The service here has been terrible. We had to wait twenty minutes for a glass of mineral water.
M: I see. Well I'm sorry to hear that. The trouble is that we're a bit sort of hands at present. Two waitresses are ill.
W: All right, but that's no excuse. My husband asked for goose and he was brought chicken instead. It's just unbelievable! And my beans weren't cooked properly. It wasn't a very enjoyable meal at all.
M: This is most regrettable.
W: Look at this bill. We've been overcharged. We only had one dessert, not two. Can you check the bill again, please?
M: I do apologize, Madam.
W: I'm afraid I'm not going to pay the service charge, or give a tip, as I don't feel satisfied with it. I'm quite disappointed as a matter of fact.
M: I'll pass on your complaints to the manager right away.
W: Thank you.
