Anything I should improve/correct?

Hi. Please read this scene and let me know if there is anything I should improve/correct,

This takes place at a bar.

Woman: I'm not interested, OK?

Man: Are you sure?

Woman: Yes, I'm sure. I think you should go back to your friends.

Man: Okay.

As the man turns to get back to his table, he slaps the woman on the butt. The woman gets up and yells after him...

Woman: Don't ever do that again, you creep!

The man just keeps walking.
