Agreed that there isn't really any harm in a generalized way. You might be surprised to learn that movie theaters (as they're currently operated) don't really get much from the ticket sales, however. I have a friend who used to be a supervisor at movie theater, and he told me that ~80% of the theater's ticket proceeds went directly to the movie distributor. This is apparently normal in the movie industry. If concessions went away, theaters would probably need to raise their ticket prices a lot. Even if you drastically cut the employees, there's still rent/taxes/insurance/cleaning. The last two could also conceivably go up in price if it became normal to bring in your own food.
