Hmm.. After you noticed the cover was locked shut, could you have called the cops? That's a robbery in progress, so that seems like a valid reason to call 'em. From there, they could have retrieved your money
Jeez, dude. I hope you're just having a bad day. Relax. Have a party with some friends. Play some guitar. Paint a self-portrait. In other words, try to be happy. If you don't care about others, they won't care about you -- and that's a rather scary position to be in.
