A:
May I help you?
B:
I would like a pair of navy blue socks.
A:
I'm not sure that we have your size in stock.
B:
I wear a ten sock.
B:
Let me look.
B:
I'll take a white pair, if you don't have navy blue.
B:
No, I'm sorry. We are out of both colors. I have a yellow pair left.
B:
No, thanks. I'll have to come back.
B:
Anything else?
B:
Yes, I would like to look at a handbag.
B:
Handbags are on the third floor.
