Good morning. Is there anything I can do for you?
Good morning. I am looking for a pair of trousers for my son. Could I see that pair hanging in the window?
Sure sir. Is this the pair you meant?
Yes, that's it. What are these trousers made of? My son's skin is quite sensitive, so I have to be careful about the material of the clothes he wears.
These are made of cotton, sir. These are made by a famous children's brand called Wonder World. It's a very popular brand because of the good quality material.
Oh, that's good. What other colors do these trousers come in? If you have blue, that would be great. Blue is my son's favorite color. I'd rather not have black or gray.
Uh, these come in blue as well. Here you are, a blue pair.
Thank you. And one last thing, how much do the trousers cost?
Well, they were originally 150 yuan each, but they are now on sale 20% off.
That's great. I'll take them.
