Delia Tsai: Would you give me my bill, please? Restaurant Waiter: Of course, madam. I have it right here. Delia Tsai: Let me see. Excuse me, but what is this for? Restaurant Waiter: That's the roast beef with baked potato. Delia Tsai: We didn't order that. All we had was one roast chicken dinner, and a T-bone steak with fries, and some onion rings. Restaurant Waiter: Oh, there must be some mistake. Sorry about that. I will deduct the roast beef from the total and be right back with you. A few minutes later. Restaurant Waiter: Madam, here is your bill. Is the service charge included in the bill? Restaurant Waiter: Yes, it includes a 10% service charge. Delia Tsai: I see. Do you accept credit cards or traveler's checks? Restaurant Waiter: We accept credit cards and personal checks, but not traveler's checks, I am afraid. Delia Tsai: OK. Here's my VISA card. Restaurant Waiter: Do you need a receipt? Delia Tsai: Yes, please. Restaurant Waiter: No problem. I will be right back. Delia Tsai: By the way, we can't fi nish our French fries, roast chicken and onion rings. Can I take the leftovers1 home with me? Restaurant Waiter: Sure. I'll box those up for you in just a moment.
