Which room did the man take finally? Which is the earliest day the check can be cashed?

M: Is No. 2 meeting room available this afternoon?
F: Let me see... Mm... No, the Production Department will have a discussion at 2:30.
M: Then what about No. 5 meeting room? How big is it?
F: It can only hold 15 people.
M: Oh, that’s a bit too small. We have about 30 people.
F: I think No. 3 meeting room will be available at 3 this afternoon. Is that OK?
M: No problem. Thank you.

M: Can I help you?
F: Yes, I want to cash my check here.
M: OK, but this is already Friday today, and it usually takes three or four working days to confirm a check. So your check can be cashed by next Wednesday or Thursday.
F: Oh, my goodness, I really need some cash on Monday. What can I do... ?
