Our neighbor was having some work done to his house, while he was away on vacation. The workers had to shut the water off to his house to do some of the repairs, and hooked a hose up to my outside faucet, without asking us if it was ok.
As soon as I noticed it, I went and unhooked the house, coiled back on his property, and threw a lock on the handle, so it couldn't be used. Told the workers I didn't appreciate them using the water I pay for without permission.
The workers tried to run the house across the front of my house to the other side of the front yard (whoever built my house was really on top of making sure you could access everything from everywhere...three outside faucets (one on each side of the house, and one in the backyard); three lightswitches for the overhead kitchen light, all within five steps of each other; seven electrical outlets in the kitchen (not including the stove, fridge, disposal and dishwasher outlets); and 4 lightswitches in the master bath (one for the tub light, one for the shower, one for the sink lights and one for the closet/toilet lights...only the tub one is far enough from the others to take steps).
I unhooked that one, coiled it up and put it in my garage (the other end was sitting in the driveway). Locked the other faucet too, and the one in the backyard for good measure.
A couple days later, they ran a heavy duty extension cord to the electrical outlet by the front door. I unplugged it, and called the company to come pick up their property. Should have kept the cord and hose, they were good heavy duty ones. The company apologized, and I ended up with a water bill $30 over the usual. My electric went up the next time the budget billing was up for review (they do it every 6 months).
