appearance is important but how you treat the customer is also very important, there was an electrician in my old firm who would clime out of his bin with wheels enter the customers house with the smoke hanging from his mouth, and would say things like is that kettle f****d or what?
there was also the electrician who was short of some flexable cable at 4:30 friday afternoon and so asked his customer nicely if she would care to set her vacuum cleaner up as his was broken, when the customer was in the other room 3m of flex was cut off the vaccum lead!!!!!!!
