W: Excuse me. My watch stopped running and I’ m not sure what’ s wrong with it.
M: Well, let me have a look at it.
W: OK. It’ s a new watch. I’ ve only had it for about a year.
M: Hmm, it seems that it just needs a new battery.
W: Oh. That’ s a relief. I was hoping it wouldn’ t be broken or something. How much is a new battery?
M: It’ s $6.99 plus tax for a battery.
W: Oh dear, that seems like a lot. My friend said she paid about $3.99 plus tax for a battery.
M: Well, she may have. But we are a watch repair shop and we install your battery and then guarantee it for a year. If you have the watch cleaned here, we guarantee it for an additional three months.
W: Well, I guess you get what you pay for. I’ 11 get my battery here. How long will it take to put it in?
M: Usually I can do it right away, but right now I’ m way behind in my repair of a large shipment of watches. They all need to be fixed by this afternoon. Can you leave your watch here until about 5:00 p.m.?
W: Oh dear, I’ m afraid I can’t. I need to get back to work and I have to work this evening, so I couldn’ t pick it up by five. And I have to have it by tomorrow.
M: Well, then maybe I can just squeeze it in now. It’ 11 only take a few minutes. Can you wait?
W: Oh, I’ d really appreciate that. Sure, I’ 11 wait.
M: OK. Just sit down over here. I’ 11 have it fixed in a few minutes.
W: Thanks a lot.
