Bob: Can I have a word with you for a minute, please?
Tom: Sure. What is it?
Bob: Well, it's about your rubbish bin actually.
Tom: What's the problem?
Bob: Well, I'm sorry to say this, but it stinks and I just can't put up with it any more.
Tom: It's full of rubbish! What do you expect?
Bob: You could put your rubbish in a bag first; so it smells less. That's what I do.
Tom: But bin bags cost money! It doesn't cost me anything to throw my rubbish straight into the bin.
Bob: Yes. I appreciate that, but the smell is offensive and very annoying. It drives me crazy!
Tom: I see. Sorry about that.
Bob: Also, the smell attracts flies and other insects, so it could become a health risk.
Tom: That's a fair point. OK. I'll use bin bags from now on.
