the what pisses u off thread

People who, for whatever reason, can't understand the concept of an express lane. I love going to check out with just a gallon of milk, a dozen eggs and maybe a couple more items (well below the 7/10/12/20 item limit), only to be cut off by some dipshit with a cart full of stuff. I can't think of how many lives I've saved in grocery stores under such circumstances (by not beating them to death with a succulent country ham).
