This morning I was in Harbor Freight Tools. The line seemed abnormally
long and one register had a "Cash Only" sign on it. It was also very
quiet.

The Point of Sale system was down. They said it was down at all stores
and it had been down since Friday. They were writing up bills of sale
by hand, and using a calculator to calculate 25% discounts, sales tax,
and totals. I wanted to tell the cashier that she could multiply by
0.75 and that she didn't have to multiply the price by 0.25 and then
store that and then subtract that amount from the full price, but the
last time I tried to explain that to a cashier at CVS she insisted
that it wouldn't be right.

You're implying the cashier at HF was not so bright.

Cashier was being paid by HF being there.

You were getting srewed by HF being there.
