Cheers was in its time groundbreaking and was filmed before a live studio audience in fact. Canned laughter was getting under people's skin at the time. When I lived in Santa Monica a neighbour had done several years on Cheers and Fraiser in production roles. But I get what you mean with a lot of other shows.
I've never been someone who can sit at a bar stool for long, I used to play pool but I've always had a soft spot for the whole nowhere bar. Films like Trees Lounge are among my favourites. There is something about the little towns where the world comes to you. I liked living for a while in Key West but Truth or Consequences NM was really special and almost nothing at all happened but every day was a laugh somehow.
