What do you guys figure is fair for a minimum time charge.
I was called by a developer to provide a stamped letter of opinion about a gas vent. The inspector had required it. He asked about my hourly rate and I told him. But when I billed him it was for my minimum 4 hour charge and he hit the roof. Wanted to pay only half.
While I was only on the job for 20 minutes, it was a 30 minute drive each way, 20 minutes waiting for him to get off the phone, an hour writing the letter, etc. What with time away and every thing I have always figured any time I went out on a job it was effectively half a day. I know some engineers charge bucks just for the stamp.
