A:  Good afternoon.  May I help you?

B:  Yes please.   How much is this hat?

A:  Let’s see.   It’s 22 dollars and 95 cents.

B:  I see.   Do you have it in a smaller size?

A:  Yes, we do.  What size do you wear?

B:  I don’t know for sure, but this hat is too large for me.

A:  Please try on this hat.   It’s one size smaller. 

B:  Thank you, I will.   ………    This hat is still a little bit too big.

A:  I see.   Here, try this one on.

B:  OK,……  Oh!   This hat fits just right.    I’ll take it.

A:  Thank you very much.   Will you pay by cash, or credit card?

B:  I’ll pay cash.
