You: Excuse me, my bicycle had a sudden tyre puncture. Can you please repair it?
Shopkeeper: Sure, let me take a look. (inspects the bike) Ah, I see the problem. Looks like you ran over a nail. I can fix it for you, but it may take a little while. Is that okay?
You: Yes, that’s fine. How long do you think it will take?
Shopkeeper: I should have it fixed within the next hour. Would you like to wait here, or come back later?
You: I have to go to school, so I’ll come back later. How much will it cost?
Shopkeeper: It will be around $10. Is that okay?
You: Yes, that’s fine. Thank you for your help.
Shopkeeper: No problem, see you later.
