Excuse me, but do you have this shirt in blue?
Yes, we do. But only in small, large and extra large.
Oh, darn. I was hoping to have it in a medium size. It would really go well with my bag.
Well, we may be getting more in next week. Would you like me to check our computer?
Oh, yes, please.
OK. Yes, it looks like our manager has ordered more. We should have some in medium by next Thursday.
