Don't ever lean back on a chair so far that it's on 2 legs. Being the burger whore that I am, I ended up eating at work before my shift started. As usual, there was employee conversations floating around the bar. One of my co-workers had a sudden fetish for leaning back in his chair while we all talked. Eventually, he had leaned back so far the hind legs gave way. He grabbed the wooden skirt of the bar counter to pull himself back up. The next thing I knew, I saw a size 10 skater shoe sweep over the bar and a plank of wood flipping toward the floor. He fell so hard that he pulled the damn thing off. Nice one...lucky for us it wasn't a customer's boner or I'd be working in retail....ick.
