I used to have a Mustang that was parked outside close to the street. Someone used to steal my gas a little at a time through a hole they drilled. They put a screw and rubber gasket to keep it from dripping. Over time the screw got bigger and bigger . This was in the 80s before cheap surveillance cameras were widely available. Tried to catch them but never did. They never took more than a gallon or 2 at a time.
Your neighbor appreciated the lawnmower gas.
