M:Good morning, Miss. I'd like to speak to the manager.
W:I am the manager, Sir. How can I help you?
M:Oh, really? It's this radio. It doesn't work.
W:Mm...did you buy it here?
M:What do you mean? Of course I bought it here. Look, you switch it on and nothing happens.
W:Could I see your receipt?
M:Receipt? I haven't got one.
W:Oh, you should have ,got a receipt when you bought it.
M:I perhaps did.I must have thrown it away.
W:Ah, well, have you got any other proof of purchase, the guarantee, for example?
M:No. It must have been in the box. I threw that away, too.
W:Oh, dear. You really ought to have kept it. We need to know the exact date of purchase.
M : What? I only bought it yesterday ! That young man over there served me.
Oh, I paid by cheque. I've got the cheque stub.
W:That's all right then. Did you check the radio before you left the shop?
M:Check it? No, it was in the box. I hoped it would work. It wasn't a cheap radio. It's a good make.
W:You should have checked it.
M:Come on! Do not tell me what I should have done, and do something!
Either give me my money back or give me another radio.
W:There's no need to get aggressive,Sir. Let me look at it...mm...you see this little switch on the back?
M:Yes?
W:It's on"main", and it should be on"battery". You really should have read the instructions.
M:Oh!
