You have to love when they also decide to do something else "while you're there anyway". For example, change a dimmer. Well it just so happens I carry alot of dimmers on my truck. I go out, get the dimmer,change the dimmer charge handsomely for the dimmer. The customer is shocked and I have to explain that if it was some other contractor that they may be paying $65.00 an hour for them to shop for the dimmer plus the cost and typical markup on the dimmer. In addition now I have to restock that item back on the truck. I dont just go out in the garden at my house and pull one from the dimmer tree.
