Here is a video. Watch it and try to understand the conversation without using subtitles. Take note of some useful expressions used by the shop assistant and the customer if you can. Then try to answer these questions:

-What is the customer looking for? 

-What clothes does the shop assistant show the customer the first time? and the second time? 

-What adjective is used by the customer to describe the second piece of clothing shown by the shop assistant? 

-What size does the customer need? 

-How much is it with the discount and without the discount?

-Does the customer pay by credit card or with cash? 

For the answer key, use the subtitles in the video.
