I've brought this dress back to exchange it.
That's not a problem. Leave it with me, and find something that you like.
I was hoping you'd have something on sale today.
We have nothing on sale today. But we're having a big sale next weekend.
Is the sale going to include dresses?
Everything you can see will be on sale.
I like the sound of that. I'll just come back next weekend.
The savings will be worth the short wait. See you next weekend.
