I’ve always wondered how movie theaters profit (871 words). There are the obvious rip-offs at the concession stands, which are very calculated (adding salt to popcorn sets you up for another rip-off, a drink). But, ticket sales are profitable, too, with revenue usually being split 50/50. Both of these explain why most movies are 128 minutes or less — the theaters demand it. ∞

Continental is the first airline to try out paperless check-in. Instead of a boarding pass (which we can now call a boring pass), you have a complex barcode on your phone or PDA. It’s not really going to save much paper, but it’s a little more convenient. ∞
