Anyone who has ever used the services of an electrician will more than likely complain about the cost of the work and the bill they had to pay. However, in all fairness, electricians do put up with a high risk level in order to do most of their work. When you risk being electrocuted every time you show up for work, wouldn't you want to charge for that?
