You go to the display and there's four bags left. So, with an eye to the future, you buy them all; with the plan to drop two of the bags in the Food Bank box at the door, on the way out.
This makes you feel good as you are basically a good person and really want to help your fellow human beans, eh.
BUT!! On the way to the door you catch a glance at the headlines of the "Daily Rag", stating the stock market has really gone for a poop, and food shortages "could" be eminent.
Do you drop those two bags in the Food Bank box ?
