I feel the same about concessions. I realize it might all be calculated to the penny for peak income but I would be more keen to regularly buy concessions if I wasn't paying close to $20 for a soda and a popcorn. I would think dropping the cost a bit might increase the number of folks buying. (The margins on it all are what really piss me off.)

I also wish it wasn't essentially a flat price for everything. A small, medium or large anything is generally just fifty cents to a dollar away from any other size. I want a small soda and popcorn I get pressed to size-up for that extra few cents to get a gallon/barrel of each.
