Walmart would irritate Mother Teresa. That said, maybe it's just Walmarts in the South. I was up North for a few weeks last year. Went to a small town Walmart and not only were employees friendly and helpful, they were astonished by how shitty Walmarts are where I live. I also don't recall any irritating customers.

Hope that kid shuts the hell up soon. I'd think he'd wear himself out eventually with all that screaming. Not sure when that became acceptable parenting, to let your kid run around screaming constantly. If I'd done that as a kid, no doubt my parents would have told me to shut up. If I didn't listen, they would have followed up with a time out or if I back talked, perhaps the ol' bar of soap in the mouth.
