my dealer horror story:
I had a '63 Corvette conv back in the 80's that was a body-off restoration, just about everything that could be replaced was.
I took it into a Chevy dealer 'cause, at that time, no one else could (or was willing to) do a rear wheel alignment on the IRS. I asked to have the front & rear alignment done.
Service writer says I have to leave the car all day 'cause "it's old & they're going to have problems with rust, seized parts, etc... I told him it had just been restored & I'd wait.
The interior had just been done so I put a beach towel on the floor, a blanket over the seat, and a couple rags on the console.
When it was done the alignment guy wanted to test drive it & I said no, I trusted the quality of their work.
I paid-up, went out to the car & the interior looked like a herd of cats had been fighting. The towel on the floor was pushed out of the way, the blanket was laying across the passenger seat, the steering wheel had greasy/oily finger print residue everywhere & the towels I left on the console had not been touched.
I popped the hood & found one of the steel valve covers dented where a wrench hit it when the guy was loosening-up the upper control arm.
I went back to the service writer & bitched. HE told me there was no way of knowing if the valve cover was already dented. I pointed to the car, pointed to the engine, pointed UNDER THE CAR ..... you could eat off it anywhere & all I got was attitude.
I wrote a letter to the owner & never heard from them so I trashed them every chance I got at every meeting, every car show, every multi-club picnic and eventually the place was sold.

new story but short.
Took my Accord in for a warranty transmission replacement during the summer & when I got it back it was pulling to the right. I checked the tire pressure and found the LF had over 50 psi (religiously kept at 32psi), at least that's as high as my gauge goes. I started bleeding air & the escaping air was hot .... damn hot.
I checked it later that night & brought it up to 32 & called the dealer the next day. Service writer said there was no reason for the tire pressure to be touched for a transmission R&R, I said "do you think I'm calling you just to hear your voice?" Got no satisfaction & I won't go back unless it's a "dealer only" type repair.

last comment: a dozen donuts every now & then certainly helps get the job done quickly & done right (small shop close to where I work) and nobody groans when they see you coming.
