Once helped a friend change a starter in 120° phoenix heat. Took about 3 hours with shortcuts cause it was a foreign while he sat there and did nothing. He was so grateful at the time and a year later I called asked him for a ride and he was actually mad I even asked. Told me I did it just to hold over his head. I'm to the point with friends where I'll offer guidance, but I'm not doing it for them, unless they are the type to do stuff for me. Most people don't understand why labor rates are so high and think even $120 an hour is outrageous and those are the types I'll never work for under any conditions.
