I hate shopping at Wal-Mart, chiefly because I can never get out of the place without crashing my cart into somebody else's. These collisions and near-collisions usually take place as I'm turning the corner of one of those overcrowded aisles. And getting from one end of a narrow aisle to another with your cart presents another logistical challenge.
So I'm guessing there isn't gonna be a Wal-Mart in Riyadh anytime soon. Unless it's for men only. Read about the hazards of shopping while female in Saudi Arabia.
