Pothole inspection? I haven't heard of that.
I personally don't trust the car wash guys at the dealer. I always wash my own car.
$39 for an oil change is ok at the dealer. They probably use dino (regular) oil, and not the synthetic stuff. Obviously it's less expensive at a private service shop, and even less $ if you do it yourself.
I've never used Turtle Wax Ice. Waxing, to me, is like sunblock - the key is to regularly reapply. I've always been pleased with Meguiar's stuff.
No clue about lof. I'd hope that if the guy is a tech, they at least gave him a spelling test.
This is blinker fluid:
