I got a call from a customer and his english was o.k. at best.So i go out there for a fee to diagnose the problem with his 100amp breaker not holding.He had vandals steal piping and wire for the house.So i told him that was the problem and i will e-mail or fax you a estimate to fix it.That will be $220 please.He was like you came here to give a estimate.I said no i came here to diagnose the problem.I drove a hour and a half and i explained to you that this was what it would cost for me to come out and diagnose the problem.Well he refused to pay blah blah blah so i told him all take off %50.So $110 better than nothingI think next time i can't really communicate with someone on the phone i will pass.Also i think i'm driving too far for jobs??Should you always give a estimate on the spot or is it o.k. to tell them you'll e-mail it or fax it?Any suggestions please.Thank you.
