He's not talking about that. He's talking about the fact that, at any Wal-Mart you care to patronize, you'll find that while they have sixteen or twenty tills installed and ready to use, they have maybe three actually staffed and available for checkout, so you end up standing in line for five or ten minutes even when there's hardly anyone in the store, and when it's busy you get to choose between waiting half an hour and taking your business elsewhere.
"Taking your business elsewhere" from Walmart is hardly a decision that is ever made.
I never go to Walmart because of this. I most of my shopping at Kroger and if I need something they don't have, I go to Target or Amazon.
That and the horrible fucking cards is the reason I don't shop at wal-mart unless I absolutely must.
seriously, I bet in the last 10 years I've never had a wal-mart cart that didn't have problems.
