Seriously. Fuck the fats in the pool. We have a small 4 lane 25 meter pool. When I go to the gym (after work), you are usually forced to share a lane, which is not really a big deal. Do you know who you cannot share a lane with? Fats. They 1) take up the entire lane, 2) ignore any and all etiquette about having to share a lane (they will ignore you standing there) and 3) if you are "lucky" enough to share a lane with a fat, they will be impossible to share a lane with (breast stroking, aimless backstroke type motions, etc. and they run into you).
