I grew up in a paper mill town of about 5,000. It had one single scree theatre (which is still there & run by members of the founding family).
One thing I remember about going to the movies was that the owner would almost always be at the door as people LEFT, thanking them for attending his business. It's just a little thing, but I remember that from over 40 years ago.
I'd have to think of the psychology of this, but today it seems a pretty good move. Businesses are more likely (if they even go this far) to welcome you INTO their place, then ignore you after they get your money. Dick was always busy, getting things ready for the show... but whenever he could, he made the time to show his appreciation that you took the time to spend your money at his place.
Just a small thing, but I never forgot it... and I've never experienced it at a multiplex (except ours!)
