Uncomfortable shoes

LADY:Do you have any shoes like these?
SHOP ASSISTANT:What size?
LADY:Size five.
SHOP ASSISTANT:What colour?
LADY:Black.
SHOP ASSISTANT:I'm sorry. We don't have any.
LADY:But my sister bought this pair last month.
SHOP ASSISTANT:Did she buy them here?
LADY:No, she bought them in the U.S.
SHOP ASSISTANT:We had some shoes like those a month ago, but we don't have any now.
LADY:Can you get a pair for me, please?
SHOP ASSISTANT:I'm afraid that I can't. They were in fashion last year and the year before last. But they're not in fashion this year.
SHOP ASSISTANT:These shoes are in fashion now.
LADY:They look very uncomfortable.
SHOP ASSISTANT:They are very uncomfortable. But women always wear uncomfortable shoes!
