Meh, you run into this at the convienence stores too and have for a long time. Way before all the automation came out.
It boggled me for a while cause I could do that kind of math in kindergarten (not joking) but you do see it. You'd think they'd give a simple course to new employees or at least give them the tear out math pages from Gr. 3 texts to practice at home.
What can you do?
