Highlift, I guess most of the experienced techs on this forum have FAILED by your definition. You probably are certified in many different areas of welding, but I can tell that you are not certified in customer identification or service. Reading your replies has me wondering if you didn't take too many DC Reverse jolts at work. Service mechanics have seen how equipment is treated by every type of individual out there. I personally would say that the higher a persons IQ, the lower the amount of maintainance which the person does on their equipment. The female gender does the least, probably due to the fact that either they don't want to or they feel they can't do it. People bring us their equipment to be repaired, because they feel we are prepared to do the job properly. They understand that they are going to have to pay for our knowledge and services. Many of us are certified by many different equipment and engine manufactures. Just like you, our tests to become certified are based on both past experience and knowledge of the manufacturers line. On top of that, we would not last long in this industry if our customer relation skills were not at the top of the scale. If you feel we are taking advantage of ignorant individuals by the services we offer, you are entitled to that opinion. Yes, those are some of the people who are helping us to pay our bills, just like an employer gave you a paycheck for doing your job. You have FAILED to see that as much as we are different than you, we are the same. It does not matter who the individual it is that you are giving money to, the SMART ones learn very fast who gives them the service they want and are paying for and return time after time. Time for you to realize that on this forum, when I think you are calling a "spade a spade" your talking about yourself also. Careful what you say, it can come back to haunt you.
