And it almost always DOES go wrong. Seriously 75% of the time when I'm done scanning and I press "pay now," it inexplicably says "calling for assistance" and refuses to do anything until an employee comes over. WHY?

And now assholes are intentionally taking alcohol through the self-checkout, deliberately taking up that one employee's time making him or her perform the workaround to check the items out.

And the 20+ years of "unexpected item in the bagging area" bullshit... just get rid of it.
