What is it about Walmart that makes the entire experience an absolute nightmare?

First of all, I thought it was only Sam's Club that needed to check your receipt before you left, now the Walmart employees are doing this too? Like, relax, bro. I'm not trying to steal a $5 DVD and some deodorant from your store.

Secondly, this employee is clearly just on some kind of power trip, and I'm glad the customer got this on camera. It's some weird, alpha male bullshit to say the least. If we're firing Waffle House employees for literally defending themselves, then this Walmart greeter should be sent packing.
