Theres this cardio room, which has windows all at the front (the direction everyone faces). The room joins onto the area where the water-tap is and seats.
One time i felt a little hungry so went and got a chocolate bar, sat down and started eating it. Then i looked up and noticed that there was a whole class in the cardio room of fatties. I mean they were huge. Obviously trying to lose weight, and there i was sitting right infront of them eating a chocolate bar. After most of them stopped doing their 'running on the spot' exercise and just started staring at me, the instructer turned around and asked me to move.
Probably more embarrasing than funny.
