M: May I help you?

W: Yes. Do you have these shoes in size seven?

M: I am not sure. If you can’t find them on the rack, they may be out of stock. But let me look in the stockroom.

W: Thanks. I’d like to try on a pair if you have them.

M: I’ll be right back.

M: I’m sorry, lady. I didn’t find your size in this style in the stockroom. So would you like to try something else?

W: No, thanks!
