Susan went food shopping on her way home from work. Her supermarket provides her with a hand held scanning gun so she can scan each item as she drops them into her cart. When she's done she just rolls up to the Do It Yourself checkout, lets the register read her gun, all her purchases appear on the screen, then she pays & she's out the door. No more lines or cashiers or ringing things up or packing groceries into bags. She just pays & goes. If she's really smart she'll have brought her big blue IKEA bag with her, but she rarely does.

On this trip her scanner beeped but did not record all of her groceries. She figured this out at the Do It Yourself checkout when her total was roughly fifty dollars cheaper than it should have been. The disembodied voice from within the register told her you may scan additional items now.
F*ck that. She grumbled under her breath & started sorting through her cart to figure out what had not been recorded by the scanner. She looked around, there was usually an employee who would pop over at the first sign of trouble, but instead the disembodied voice told her if you are ready you may finish and pay.

Finish and pay fifty dollars less, yes please.

No one came to keep Susan from stealing groceries, but neither did Susan stop herself. Instead she paid, turned in her gun and cooly headed for the parking lot. She knew she was wrong but kept going. Machine error was not her responsibility. She repeated this lie to herself a few times.

Susan went home, unpacked her groceries, sat down at the computer and made a sixty dollar contribution to Long Island Cares, an organization started by Harry Chapin to feed the hungry.
