Good morning! Can I help you?
Yes, please. I want a T-shirt for my son.
What size do you want?
Size L, please.
OK! What about this one?
Sorry! I don't like black. Have you got any other colors?
Oh, yes. We've also got blue, brown and white ones.
Can I have a look at the white ones?
How much is it?
OK, I'll take it.
