What kind of technicians would we be if we didn't question your theory digitalphonemike? You seem all over the place and a bit touchy b/c no one believes your theory. And you say Mastec supervisors taught you this trick? Seems to me that this would be common knowledge around the water cooler if it will increase their numbers. Sounds like a step in the wrong direction to me. You aren't trying to keep money in my pocket you are trying to add to the back charges and cost someone their job....
