Way back in the day I had a job delivering fuel oil for home heating. One stop had an underground tank in the back yard so I jumped over the fence, pulled the hose and filled the tank. Then noticed two dobies just laying on the ground by the fence. As soon as I finished with the fill and started back to the fence, both of them got up and started menacing me. Keep in mind, this is a 2" hose at 50PSI.... Filled one dobie with fuel oil at a distance of about 5', then vaulted the fence. Strangely I never got a call back to fill their tank again!
