Obscure movie related observation! :-)

This is a difference that I've noticed between movie-going in India vs. the US.

In urban India, typically, the Balcony and First class (lower level rear seats) are usually more expensive as well as usually the ones to be sold out first! Most people tend to buy the second class (lower level middle to front seats) or Gandhi class tickets as a last resort. By the way, why call the cheapest class as Gandhi class? I have absolutely no idea!! :-)

However in the US, I've noticed many Americans occupy middle of the hall moving forwards rather than toward the rear seats....wonder why?
It's quite a symbiotic relationship for desis and americans here because the seating is somewhat mutually exclusive, so we can afford to show up quite close to the show time and still get good (as in rear) seats!!

Thoughts / possible explanations welcome! :-)
