Yes that is what I meant by cowboys, but from a technicians POV I can't see too many problems.I do call outs in the job I am in, but when they are in work time I only get paid for the petrol, and for the repairs I do at the shop, as you can imagine I just get paid the normal (apprentices) wage, which isn't a great deal. So I thought this would be a good little side job. I always explain to people that they are paying for my time, and I am yet to leave a problem unresolved anyway. So I wouldn't mind not charging if I can't solve the problem since it won't happen too often. I have never had problems before with the exception of one college, people or kids watching over me doesn't bother me, nor do pets (with the exclusion of the goldfish of course)... although the occassional customer that asks me to explain what i do can be irritating, i just tell them using the most jargon i can until they get bored. As for the college they kept saying they would post a cheque and they didn't for nearly 2 months, but that could have been lack of communication within the college and I got the money in the end.
