Hi Nick you think you are hard done by contractors, my wife worked as a nurse in Q.A. Portsmouth a P.F.I. hospital. The nurses used to joke at how many men it took to change a light bulb, once the total was 7. First you had to put in a job card, then a supervisor would inspect it, then a electrician would appear with a couple of helpers, but before work started a safety inspection would take place. When before a porter would turn up with a bulb in his pocket and a step ladder.
