We all go to Wal-Mart even if some of us don't admit it.
Have you ever loaded a basket or a cart up with purchases only to see 24 checkout lanes - with a grand total of 3 of them open? Have you ever waited for an eternity at the returns counter while the clerks play Sherlock Holmes, investigating each item and each person in depth?
Whether you love or hate Wal-Mart, here is the quickest way to get personalized attention from the top dog store manager: take a video camera. I watched two girls shooting a student project in front of a Wal-Mart (they were simply using it as a backdrop). In 20 seconds or less the name-badged manager was fairly sprinting out to the front of the store to challenge the girls and ask how they dared to use his precious front wall as a backdrop.
At that point they had mostly finished their shoot but it's obvious that the fear of God has been drummed into Wal-Mart managers where PR is concerned. Yes it's private property and yes they have a right to rules and enforcement but I did find it ironic that such an immediate response could be elicited from such an innocuous stimulus.
