When in costco, people in front of me taking the whole isle must just stay in the store from open to close as they sure dont have anything to do. So I look over to the other isle to see if the traffic is lower. It sure appears to be as there is no-one over there that I can see. So I turn the cart and head to that isle. Huh???............people just appear out of thin air, lots of'm. They must be related to the ones in the other isle and just live at costco. I'm thinking that when I show my card at the door, they must activate some sort of nearsighted vision optics that were installed in my eyes when I got the picture taken for the card. No matter what isle I look at from the one I'm in, it looks clear until I get there. Beware when you get that picture taken. It makes getting behind the people of walmart in the check out line a piece of cake.
