Once in college I was out drinking with this girl (a friend) at a bar during happy hour. We wanted to go to another bar, but the waitress took forever to bring the check. We decided to just walk out. The next bar was slam packed too, so we ditched on that tab. We decided to do it again, and again, and then to make the night of it. I think we hit 8 bars for about 2 drinks each. The last bar, a cook actually chased us with a meat cleaver. I've grown up since and know it's just one of those things in life you DO NOT DO because you can screw up your bar/drinking karma and/or seriously get your ass kicked.
