farm-stand harvest

Refers to the pathetic practice of as few particularly-unscrupulous/selfish folks who go around to unattended produce-booths that typically pop up in late Summer and early Fall, carefully note which of the stands use unsecured "purely on the honor system" money-containers like screw-top canning-jars or snap-top coffee-cans, and then wait till late enough in the afternoon when the "unprotected" booths' cash-containers would logically be about the "most heavy with the day's fruit and therefore ripe for the plucking", but still a little while before the farmers would likely arrive back at their stands to close up shop and collect their money... the greedy light-fingered shysters then hastily empty out the containers into their own pockets and leave without anyone's being the wiser.

It's just too bad that you can't trust people nowadays with even fairly small amounts of cash laying around! Fruit/vegetable gardeners will do well to take steps to foil farm-stand harvesters --- one of the best ways is to n-e-v-e-r simply leave ordinary easily-opened/broken containers for legitimate customers to leave their money for purchasing the booth's produce --- instead you'll want to supply a "drop it in the slot"-based money-container, and have the container firmly/solidly fastened down so that it cannot be readily "lifted" and transported elsewhere to be forced open later. I would recommend a heavy-walled plywood or metal box with glue-covered countersink-embedded deck-screws or welded-together bolts that cannot simply be unscrewed, and have the box securely bolted to the farm-stand's main framing-timbers where it cannot be simply pried loose by hand.
