Thanks for clarifying that you have next to zero credibility with knowing much about the industry.it's full of cheap idiot owners and crooks. While obviously not all of them are like this,
A more factual statement is that because the FEW truly bad lube shops get such widespread publicity....they ALL are considered a place to be avoided. That simply is not true. Yeah, I was in the business long enough to know that your claims are baseless. None of the owners I had experience with were "crooks" or cheap. The one owner who flirted with going down that road got met with heavy resistance from me...and I proved it to them.
And if I had an owner as a boss that would not allow me...as a "manager"...to operate a honest, problem free business, with outstanding service, then I would not work there. Like I said...your friend is incompetent.
