When people leave their shopping trolley across the aisle while they peruse the shelves. LEAVE ROOM YOU INCONSIDERATE MORONS! People who stand still on escalators. WHAT, YOUR LEGS DONT WORK? NO WONDER YOU'RE SO FAT. People who constantly shout at their children in public. IF YOU ALWAYS SHOUT AT THEM THEY WILL SEE IT AS NORMAL AND NOT UNDERSTAND WHEN THEY ACTUALLY DO SOMETHING WRONG! Joggers that wear hi visibility clothing. YOU'RE JUST A SLIGHTLY FASTER PEDESTRIAN!
