I'll be honest, it pisses me off to no end. You require me to check my own shit out, then want me to show proof that I paid for it. They ask people who stand in the long ass lines to show it as well. I RARELY go to Wal-Mart and prefer independents, but that's JMO.
As for this psychopath, on SSI and probably never worked a day in it's life and probably SSDI IMO, wouldn't you like to have a taxpayer off-switch? IMO, it fits the profile of a thief.
