Describe the standards that someone must meet to do technical work for the speaker. Also express a negative view towards fortune tellers.
Anyone who does any technical work for me at all must be licensed, insured, and bonded so that I know they've met at least the minimum technical performance requirements for the position.  I also need to know that such job performers know, understand, and are able to meet minimum quality requirements.  I don't have the time or money to "experiment" with every Tom, Dick, or Harry that comes along.  Fortune tellers.....not so much.  Only idiots use fortune tellers, anyway.
