Essential Plumbing skills

When the plumber arrived to service the boiler this morning, only a brief 'Hello' on the doorstep interrupted his continuing call on his smart phone, wedged neatly between his shoulder and his ear.

By now, he knows his way round our boiler, and he managed to continue the same hands-free conversation without a word to us the whole way through the service. Once the boiler casing was back on, there was a brief inter-call period long enough to present the bill, write a cheque and even exchange thoughts on photography (the phone having a further role here). But by the time that was done and the tools being packed back, his head was again propping the phone and another conversation was in progress.

Do they teach them that at the Skills Academy?
