They see you are making monies then they want a slice too.
I never made any money on it. Not one dime. That was never my intention, either.
What happened was, we disassembled the system to ship it to the farm. Sometime later, I put two single chamber beehives in the same area. Because my landlord was scared of the bees, this caused the owners of the property to tell me I would have to start paying for the use of the land. They, stupidly, thought I would pay them to rent the entire lot, for 2 hives. Typical SEA mentality for this part of the world.
