Why Would I Expect Them To Do Math? It's A Miracle They Can Even Breathe.

"Is $6 enough to put these items on layaway?" an elderly couple asks me, dropping 5 identical items on the desk.
"You need to put 10% down. Are these items over $60?"
"We don't know." They reply.
So, I rang them up. Each item was $25 a piece, totaling $125. And these people couldn't figure out what if what they were buying cost $60. WTF is wrong with these customers? Do they shop intoxicated?
