How can we say? How do you say ?

My daughter works in an apparel industry.
A week ago, she told this story to me laughingly.

A foreign woman customer came to her shop.
The customer said "I want to buy that coat. But I think these sleeves are too short for me. Could you repair them?"

Everyone staff in the shop thought the same thing.
"Oh, what shall we do! There is no one who can speak English here.It takes one weeks for us to finish clothes repair. How can we say in English? How do you say ?"

Then, a woman salesperson in the shop said to the customer with act of courage.
"Long long OK! One week."

A woman customer said "Oh! I see. OK!"
