Auto tech/Mike’s Master Mechanics Auto Tech/Mike’s Master Mechanics Inacurate Diagnosis/Drug Use. Las Vegas, Nevada!!. Hello. I have previously posted information on Auto Tech/Mike’s Master Mechanics’ lack of satisfactory automotive diagnostic skills. I held back a very evident cause of this, but now feel obligated to inform potential customers of Auto Tech/Mike’s Master Mechanics of this. Auto Tech/Mike’s Master Mechanics does not Drug Test, or Background Check any of it’s employees. This makes their claim of being the place where “the best mechanics work” impossible. For instance the Tropicana ave. location has a lead diagnostic tech, and G-2 Smog Tech (Cory Yeargan), who habitually smokes Marijuana bofore work. Many Marijuana smokers claim that their drug does not affect their work. This is a lie, and an inaccuracy that is wrought of the dullness brought on by their habit. Read my previous report on Auto Tech/Mike’s Master Mechanics to see the gross misdiagnosis, and blatant cover-ups of the mistakes made while Cory Yeargan was high on Marijuana. Companies like Auto Tech/Mike’s Master Mechanics, and their lack of anti-drug policies, do give our industry a poor reputation. this is the reason for my continued exposure of these mechanics, and companies.
