Asking about lost property

R- How can I help you?
M- I think I left my jacket behind in the cinema last week. I was wondering if it's been handed in to lost property.
R- Where do you think you left it?
M- I'm not sure. Either on the back of my seat, or in the toilets.
R- What's it like?
M- It's blue and white.
R- Is there anything written on it?
M- Yes, there's a logo. It says 'D & M'.
R- I'll go and check for you in lost property now.
...
R- You're in luck. Here it is!
M- Great! Thanks for your help.
