Response to a comment.

This comment was left on on older post so I thought I'd respond here.

I know I'm kind of late to comment on this post but out of curiosity, do you get customers at the concession stand who are not going to see a movie that night? Not sure if this is something you can/do track. I just imagine there may be students in the UCC who just want a snack.

Yes, we sell a fair amount of stuff to people who aren't going to the movies. We sell a fair amount of popcorn to people studying or meeting in the building.

We stock some items just to sell to the general public. Red Bull and Rockstar are generally bought by studying students. We sell quite a bit during exams.

This is partly because we run at night. The variety store downstairs closes early some nights and isn't open at all on the weekends so we are the only place to buy some stuff except for vending machines.

During the summer we are the only place open at night at all on the entire campus except for the Grad Club so we get a lot of customers looking for food. We sell hot dogs during the summer only for this reason. Hot dogs are about the only thing I could come up with. Anything else like sandwiches have too short a shelf life for us to sell at a reasonable price.

At one point I planned to turn the concession stand into a mini variety store and carry things like gum but dropped the idea once I checked into it further.
For things like gum there's too many varieties and I wouldn't be able to carry very many. Plus I hate gum, it should be banned if people don't stop sticking it to everything.
Things like Potato Chips would cannibalize popcorn sales.
Pretty much everything else a variety store sells that we didn't already sell I didn't think we would sell enough of to get around shelf life restrictions.
