I'm all set 

A New England phrase that is usually heard in or around shops. It's used to take the place of "no I don't need any help" or "no thanks."

It confuses the hell out people from the rest of the country. Especially the Southeners.

Shopkeep: Can I help you with anything?

Shopper: No, I'm all set, thanks.
