I go in for tire repair and the man asks about my windshield wipers....?

I have a work car that I take to the dealership for oil changes. They would ALWAYS come out with a "dirty" engine and cabin filter. They wanted something like $120 to replace both so I reject. Then the next time I replaced both (with the company card) for about $45 before taking it in just to see if they would show them to me. They didn't.
Dealer did the same thing to me, when I took the wifes Jeep in for an oil change.
Stopped at the local parts store and bought the filters on the way home.
They had never checked the air filter, it still had dust on the housing and no fingerprints.
Finally got the sob out, and it still looked like new, replaced it anyways because it was such a pain to get to.
The cabin air filter was super dirty, wife smokes so that would explain that one.
