W: Hello, sir. What can I do for you?
M: Hi, Uh… I have this cassette player here that I bought about six months ago. And it just ruined four of my favorite cassettes.
W: Oh dear, I’m sorry.
M: So I… urn… want you to fix it. I’m sure it will be no problem, right?
W: Your sales slip, please?
M: Yeah, here it is.
W: I’m sorry, sir. Your warranty’s expired.
M: Well, it ran out ten days ago, but I’m sure that you’ll… you’ll fix the machine for free, because the machine was obviously defective when I bought it.
W: I’m sorry, sir. Your warranty has run out. There’s nothing I can do,
M: No, no, look. I didn’t drop it off a building or anything. I mean, what difference can ten days make? I mean you can…
W: Sir, I’m sorry, we have the six-month rule for a reason. We can’t…
M: Well, surely you won’t hold me to ten days on this. You can bend the rule a little bit.
W: Make an exception for you, and we’ll have to make an exception for everybody. You could say it’s only a month, it’s only two months…
M: I just lost twenty dollars worth of tapes.
W: Sir, I’m sorry, it’s too late. There’s nothing I can do.
M: It actually ate the tapes. I mean, they’re destroyed. Paying for this is adding insult to injury. It’s… it’s a good cassette player, I mean, I can’t pay for this.
W: Sir. the rules are the rules. I’m sorry, but there’s nothing I can do.
