[speaker001:] I would like to return this pair of shoes.
[speaker002:] Do you have a sales slip?
[speaker001:] Here it is.
[speaker002:] Sorry, things on sale are not allowed to be refunded or exchanged.
[speaker001:] Oh, but this pair of shoes are a bit too tight. Could I change them for something bigger?
[speaker002:] All right. Wait a minute.
