Oh yeah, I have noticed that they are often rude. My brother was so peeved off when one flipper guy rolled a cart on his foot and did not apologize. I saw a couple of pro flippers hitting a store nearby, both of them female probably middle aged. The store arranged shirts on small racks one behind the other (there were about 4 aisles of shirts) and they had a brilliant scheme which was to park the cart inbetween the racks facing north south (with racks going east west). Simplest way to stop people picking, block two whole rows. While they amused themselves with shirts, I amused myself in the sport coat / suit section and found a recent Giorgio Armani Black Label Sport Coat and a Zegna Mainline Cashmere Overcoat. I also picked up a Dunhill runway type bomber jacket. I felt like walking by and saying "check what you two morons just missed out on" .
