the ability to remotely disconnect
Twice in the UK I tried to have a water meter installed but to no avail. On both occasions a contractor turned up and asked me whereabouts the main water pipe entered the house. I would say "I don't know", he would say "Me neither" and he'd leave straight away. I suppose I should have stopped paying my water bill just to see what would happen when they tried to cut me off without knowing where the pipes are.
