I think Wal-mart is the only company that doesn’t maintain their shopping carts. They’ve come up with a trick that will encourage you to endure the punishment of wobbly wheels for the shopping duration. The trick is they cover the solarium with a bunch of uneven stone tiles. You won’t notice the wheels are busted until you’ve been been distracted by a Wal-Mart elder and the lure of cheap candy, bananas and detergent before hitting the smooth surfaces. They figure that you’ve traveled all this distance from the corral and you won’t walk back to get another. You might risk offending the elder and get scolded: “Well, back in my day, we had to strap saddle bags on a mule when we wanted Doritos from the General store, I think that buggy will do you just fine sonny boy”.
Sometimes you get lucky and there aren’t many buggies in the corral at Wal-Mart. This gives you a bit of smooth surface to do a little test run to see if all the wheels are straight. I’m sure Wal Mart will catch on to this, and extend the rough tiles into the buggy corral. It’s really only a matter of time before Wal-Mart becomes just a rough uneven terrain of shopping on dirt floors. Then you won’t notice there are no wheels on the buggy at all.
