Can I help you?
Yes, I'm looking for a sweater in a medium size.
Let's see. Here is a nice white one. What do you think?
I think I'd rather have it in blue. Oh no, the pink one. It looks better.
OK. Here's pink in a medium. Would you like to try it on?
OK. Yes, I love it. It fits perfectly. How much is it?
It is $50. It will be $53 with tax.
Perfect. I'll take it.
