I don't know what his problem was, TBH, but I suspect it was coming out to do a simple 30 minute tap down job on one PMT, then finding that he had to chase around tapping down two other PMTs, and, as a consequence, have the 11 kV supply to the area turned off for a couple of hours, resulting in complaints about the power being off.
Reminds me of the superb classic line from 'Jack Regan' - "We're the Sweeney and we haven't had out tea yet!"
