Salesgirl: Good Morning! What can I do for you?

Sarah: Could you let me see that green dress? I saw it in your window and I like the style and the colour very much.

Salesgirl: I`m afraid, this dress will be too big for you. May I show you another dress in green? I think this one will fit you.

Sarah: This is another style. Let me try it on in your fitting-room. I think I like it too. It is very nice.

Salesgirl: I see, you like the dress. It looks very fine on you.

Sarah: I will buy it.

Salesgirl: Do you want anything else?

Sarah: Could you show me that light white shirt? I would like to buy it for my son. May I bring it back tomorrow, if this shirt doesn`t fit him?

Salesgirl: Sure, you can. It it doesn`t fit him, you can make a refund or exchange it.

Sarah: All right.

Salesgirl: Would you pay cash?

Sarah: No, I would like to pay by my credit card.

Salesgirl: Fine. Thank you. Here are your clothes.

Sarah: Thank you, too. Good bye!

Salesgirl: Good bye!
