My son and I picking melons to sell along the road in front of our home, we use a honor box system to collect the money. The "honor box" is a ammo can with a lock and a slit just small enough to slide money through. We have also found adding a trail camera to the trailer greatly improved the amount of honesty because anyone caught stealing will have their photo posted on Facebook. We still have theft the trail cam makes a world of difference.
