Hell has frozen
There is a double standard in this world. Never would an engineer think of working for free of severely discounting his services to crack head prices. Kirk has said what he gets paid to do a knee replacement in the past. I don't remember the exact figure but I do know he does not get paid enough for the investment he has in school, time, and skill.
In my position I have the option to turn away people who don't pay. I generally don't turn them away, we will work something out. If you come to my office in a nice new car, with a pack of marlboros in your pocket the proceed to complain you have have no money, you will be quickly shown the door. I lol when I see someone complain they cannot afford health insurance but the drive a new car they are financing and paying high insurance on.
