I think all the shops do that now. People are lazy and time is money. I always viewed the torque stick defense as a load of garbage. Sure they may have them but I doubt very much they get used since no matter where I go, I have to use a large breaker bar to break them loose and torque them to spec.
In my experience, 99% of the people doing any job are very good people, but training has gone to hell. The younger kids think they know it all from the Internet, and a lot of the shop owners think of them as disposable. A different world than when I grew up. But if you hold out your hand, and provide a little friendly advice, my experience is that the younger folks are sponges, and suck it all up, usually with a smile and a thank you.
And an engineering thought on torquing bolts. Very rarely is the bolt itself actually carrying the load across it. The bolt is pushing the two pieces together, and the friction between the two is what keeps them in place. Mechanical engineering, 101.
You may not believe it, but every piece of “that,” whatever “that” is, is designed with flex, motion, and catastrophic failure in the equation. More specifically, hard to believe, the bolts actually bend, but it’s a teeny amount you could never see. A lot of the residual and ongoing strength is from not exceeding the design. The design that determines the torque is based on having the unit tight enough to hold everything together safely, but far below the failure point of the nut or bolt. Over tightening increases the point of failure dramatically.
Aluminum and mag wheels are particularly susceptible to deformation, and fatigue around the bolt holes, if they are constantly over torqued.
I’ve also used wheel spacers on some of my custom projects. The wheel spacers typically have a torque setting 10 or 20 pounds higher than the wheel nut torque spec. I always clean the iron/steel surfaces at least with a wire brush, sometimes with some sandpaper, I torque the wheel spacers down in steps, and I use red thread lock on the spacer bolts, and I also smear a little on the back of the wheel adapter. I let that sit overnight, and then I torque the wheels to the right torque setting. I had a couple of adventures when I was younger, but I’ve been doing it this way for probably 20 years, and never ever had any issue whatsoever.
I have a couple little cheap 3/8 drive, 20 V impact wrenches. If I have to, I loosen my bolts with a breaker bar, but then spin them off for convenience. When I put them back on, I spin them down with the torque wrench, but just till they’re snug. Then I almost universally use a half inch drive torque wrench to get them in the right place. When I had heavy duty trailers, and on my F250, I even tighten the Lug nuts in steps. If I remember, the F250 requires 140 foot pounds. I’ll tighten them to 100, then 120, and then 140, always crisscrossing across the pattern.
I don’t mean to sound like a know it all, just trying to help folks who are new at it.
Hope it helps
BTW, I have a a lot of knowledge on trailer, couplers too…
