Patrick: I'd like to buy a bottle of Centrum, a dozen tooth brushes, some baby's wipes, and a small bottle of aspirin.  
Clerk: Centrum? We have bottles of thirty and one hundred tablets. Which kind do you want?  
Patrick: Give me one bottle of one hundred tablets.  
Clerk: And what kind of toothbrushes would you like?  
Patrick: Can I have a look at them?  
Clerk: Sure. This brand is supposed to be very good, but they're expensive. Those are new products. They come in several colors and sizes. There is also hard, soft, and medium.  
Patrick: Are they cheaper?  
Clerk: This one is 10 % off. That one has no reduction, but you can get a free tube of toothpaste with six toothbrushes.  
Patrick: So if I buy a dozen, I'll get two free tubes of toothpaste?  
Clerk: That's right.  
Patrick: Good. I 'll take a dozen of them then.  
Clerk: And here is your aspirin. What else did you say you want?  
Patrick: Baby's wipes. Johnson's.  
Clerk: Anything else?  
Patrick: Well, actually I'd like to buy some vitamins for my son. He's five months old. Can you suggest any?  
Clerk: Sure. Here you are. This one is excellent. Just mix one drop of it with milk. 
Patrick: Thanks. That'll be all. |
