@Humpleupagus @stoner713 @LM9 @EvilSandmich circling back to the op
they wont enforce this equally, and i bet you it'll be used to stop dissidents from purchasing items, at the very least its going to collect biometric data to sell and its going to record who buys what

wait for it, they'll start selling a lot of ammunition and everyone buying, even with cash, will be recorded, so the feds know roughly what calibers they're up against in what areas

mark my words

sometimes i use self checkout especially if its some nig'ed out place like walmart
