I'm assuming this happened in the states... In Canada you do see this, but definitely not as much, especially in schools. While I'm studying I ALWAYS see people leave their booth/table and have a nice shinny macbook sitting there, with an iPhone 4 right beside it. They come back in 15 minutes or so and continue whatever they were doing. No one touches their stuff. This is how the world should be... These self centered *******s need to get a life and stop causing problems for innocent people. I really hope your phone does turn up dude.
