Me: Ah, you're selling the... (programmes)
Her: Yes, do you want to buy one?
Me: Yes, hang on, I just wait until the... er... (people have got out of my way)
Her: Sorry about that. So do you want to buy one?
Me: How much do you want me to...?
Her: (Baulking) Er... well... you know, it's up to you, really.
Me: (realising how creepy the above line went) Sorry, I'll finish the sentence. How much do you want me to PAY?
Her: (relief) Three pounds.
Oh, the misunderstandings...
