In our little midwest town, a local farmer puts his vegetables on a flatbed at an intersection near town. The stand is un-manned, so everyone is on the honor system to take correct amounts, put payment in a metal box he has bolted to the flatbed, and to not steal the payment box.
It must work, because his product is there every summer and autumn, year-after-year.
Societal trust a beautiful thing, and awful when its gone.
But on the state route that are heavily traveled and not surrounded by houses you find the stands are all manned.
Neighbors look out for each other. When you have no neighbors you have to look out for yourself.
I saw that a while back in Vermont.
Picked a few cucumbers and tomatoes went to put my money in a box and saw a bunch of cash just sitting there waiting for me to steal.
I was amazed.....
That cash would last 5 minutes in my MA town...
That suggests those who are after the veggies are honorable, but those looking for cash need a welded-down solution.
