Lane pigs

I really, truly dislike lane pigs. Folks that design store layouts work very hard to make each aisle exactly two carts wide. When a single person with one cart clogs up the whole aisle, I get angry. Halls in most public buildings are at least three people wide. When two people clog up a whole hall so I can’t walk by, it makes me angry. These folks don’t straddle the white line when driving down a road – why on earth do they find it acceptable to do so in a grocery store, or while walking down a hall? Do we need to paint white stripes inside all buildings, so they wake up and walk straight? Infuriating!
