Because I've heard it every single day of my working life . . .

If there's a cashier that's having trouble finding the barcode on an item. . .

If there's a salesman who needs to step away and ask a manager what discount he can authorize . . .

If there's a sales clerk who isn't sure of a price because the tag is ripped off or you grabbed it out of the wrong bin . .

If there's a cashier whose scanner isn't working quickly enough, or who stops to correct an obvious error . . .

If any of these things are going on, and your brain tells your mouth to spit out some variation of:

"Huh chortle chortle. I guess it must be free then eh?"

Then . . .

YOU ARE A DICK.
