Opinions please

Mechanic friend up the road works out of his shop at the house doing side work. Ford trained when he was a kid, working for a company maintaining trucks for total about 30 years. Particular about who he works for. I trust him, really wouldn't want anybody else working on my stuff. Besides the Mopar. That's the hobby toy I enjoy working on. You know, the wifes car and my truck, tractor. Whenever I ask him how much after a job, he always says, man I don't know what to charge my friends. So I say how many hours? He tells me and I offer 40-50 bucks an hour. He rarely takes it. Point is, eff your guy. He doesn't know a good mechanic when he's got one. I don't go to friends looking for deals. I go because I trust them. Eat it and move on, no more good deals for him. My 2.
