At the checkout counter

Hello! I want to buy these sandals. Can you please make a bill?

Sure ma’am. Have you checked the size?

Well, no I didn’t. They say size 7,...that’s my size.

Hmm... I think you should try them on just in case.

That’s a good idea. Let me try these on. Are you going to make the bill in the meanwhile?

I’ll have the bill ready for you when you get back.

Thank you.
