Yes, that is probably the reason that one cannot find a parking slot at Wal Mart.
I thought it would've happened at Sam's Club.
Actually you are right, they do a big business and I must admit I still shop there. Probably would shop somewhere else but they are the only discount store in the area.
I still think their service is awful.
Nobody goes there any more because you can't ever find a parking spot.
