answer: #Person1# wants to return the trousers but #Person2# says #Person1# can only have an exchange and promises it will be in time.
documents: #Person1#: I bought these trousers here on Wednesday. When I tried them on at home, I found them too small for me. Can I return them and get my money back?
  #Person2#: I'm sorry. You can't because you bought them at a sale price. However, you can exchange them for a bigger size.
  #Person1#: I have already looked around here, but I can't find the proper size for me. I have to wear them at my co-worker's house warming party this Saturday.
  #Person2#: Don't worry. If we don't have a bigger size here. I'll find another store that has the right size for you and you can pick them up by Friday.
