However, for the sake of those sharing that monstrous, but frequently crowded space, please be aware of a few things:

1. Do you know where your cart or trolley is? In other words, have you gone off and left it in the middle of a traffic area as soon as you spotted something you just have to have? Most other shoppers have a cart of their own and aren't interested in maneuvering around yours, so be a dear and keep it with you -- close to you.

2. "Oh, my gosh, would you look at that!" syndrome. This is when people find something so intriguing that they stop in mid-step to look closer. No thought is given to those who might be following behind (Shopping cart pile-up on aisle 3, please) or wish to pass by (Clogged passage way in sporting goods). Just as when you are driving a car, move to the side (with your cart) before you stop.

3. In the fable about the tortoise and the hare, the tortoise came out ahead. Not necessarily so while shopping in a warehouse store. Some of you may be there to browse without hurry, while others are interested in getting in and out in record time. Whatever your speed, watch out for others. If you are meandering, stay to the side of the walkway and allow others to move past you. If you are setting land speed records, be careful not to cut others off or clip heels with your shopping cart as you fly by.

4. Try not to look really, really silly while you are shopping, and by that I am referring to those people who are hunched over their carts and chatting on their cell phones as they attempt to push, walk and talk at the same time. What could be so important? If you have to make a call -- "Are we out of peanut butter?" -- or have to take a call, then move to an out of the way area to take care of your business before continuing on. 

Is this on the level of brain surgery? No, not at all. But it does require some thought and awareness of other people. After all, they are out shopping too.
