so your airlines thread reminded me of this kid from college. I was at a conference during with some other students (they were more into the party side of it, I was newly graduated and mostly there to accept an award...and fun too)
anywhoodles, one of the guys in the group was really into getting the hotel rewards. Like super duper. He didn't like the drinking part so while the other guys in the room drank one night, he sat on the bed in pajamas reading aloud from the Bible.
One of the guys got weed at some point (I had nothing to do this and probably would have tried to shut it down even though I guess this was in CO) and rewards kid got a room at a different hotel. He mentioned he had a rewards card for them too.
Cool story bro, I know. But your post made me think of that again.
