If I employ a plumber to fix my bolier I would expect him to charge me X, if I then ask him to sort my cistern out at the same time I would then expect to pay X + a lot! Is there a difference?
The plumber will not for ever whinge about having to train an apprentice or expect to be paid lots mor for doing it.
The plumber will not for ever whinge about what would happen to his job if the apprentice mucks up on a boiler repair and people are killed in the explosion 10 days later.
The plumber can be paid more than an ATCO and TRE combined per hour!
There's 3 good ones.
