The word "joint" as a synonym for place?

I'd like to know in what context can the word "joint" be used as a synonym for place.

Is it used for places that sell products and/or services?

Answer

It's a very common and informal way to refer to a business, usually one that sells food or drink. "I run a burger joint in Anchorage." "Lets meet at that joint on the corner of 5th and Main." Usually it will refer to a small, casual restaurant or bar.
