Leeching wireless internet is pretty hard to not do - hell, my friend did it for a week before he realized he wasn't connected to my router, but rather the neighbors'. As long as you're not constantly streaming video or uploading large amounts of data nobody'll notice, so why not save a couple bucks a month. Blame them for being too ignorant to put a password on.

I'm pretty conservative when I'm high, so the most expensive thing I've ever bought on a whim was one of those KFC Mashed Potato Bowls. Totally worth it.
