What the hell is going on with shops?

I also love the argument about paying for all the cost of doing business stuff. What gets me there is that is all charged to the customer and then written off come tax time. Since I as the customer was the one paying for that stuff as pointed out above, shouldn't I get the tax writeoff? I don't know what the book says overall, just from the few things I have ever brought in or had done under warranty. The hours listed were always silly high for somebody actively engaged in the job with all the proper tools. I'd love to hear some specific times of what the book says for common things people here have done themselves so we could judge for ourselves your argument you get screwed with those times.
I do complain about the doctor rates as well. Last time in I timed the actual doctor time and then compared to the billed rates and shamed them on social media. Lots of people responded with "why do you care you have good insurance?" Exactly one reason our healthcare is getting so expensive. That, over use, and lawyers.
Clueless & ignorant!!...
I'd love to know what you do for a living? I bet you think you're under paid too.
Here's a suggestion: Go to trade school, buy all the tools necessary to diagnose & repair your car sucessfully & right THE FIRST TIME, (scanners, full set of hand tools, tire equipment, emissions equipment, digital meters, pressure gauges, precision measuring tools, welding equipment, A/C serviceing equipment, waste oil & anti-freeze storage containers, compressor Air tools, specialty tools needed for specific tasks you may only need 1 time but can't do without to fix the car, additional training to stay on top of an ever changing industry on & on) & THEN FIX YOUR OWN CAR & SEE HOW MUCH A PROFESSIONAL IS WORTH!! Just do it for the vehicles you own. Now multiply that for the hundreds of vehicles out there that we deal with daily. I bet you can't even name all the various systems & subsystems that are in the car you own.
Yes I am a CAR DOCTOR!! And my patients change with every year, make & model! Unlike your health care provider who has 2 models to deal with & they haven't changed since Adam & Eve! Pull your head outta your *** & walk a mile in my shoes!
Tax write off.. Gimme a break! You know just as little about business accounting too.

BTW, I'm not knocking Health care providers, they work hard & have a lot to know & have great resposibility too. I'm just making the point of how much is necessary to know in my field.
