Americans will find a way cram sugar, fat, and salt into anything to epic levels (in that order). It increases the chance of repeat customers from retards (ie fatfucks). You're absolutely right, it reduces the crunchiness. It's still there but muted, kind of like walking onto a carpet out from a tile floor. I never go to the movies anymore because outside of teenagers (some of whom are still depressingly fat), everyone is a fatfuck in a 6XL tshirt inhaling popcorn, sugar water, hotdogs, and candy.
