Won’t they be selling more sodas now?
Nope. When someone goes in, they will buy one soda and be done. Before they would buy the biggest soda as it was the “best value”, but it was also the best price point for the theater.
Now people will buy a smaller popcorn (because in their minds they won’t have enough soda to wash it down) and a 16oz soda. Instead of spending $14 for a large popcorn and soda, they will be spending $8 for a small popcorn and soda.
It will cost theaters thousands of dollars a week.
