Replying to Jerry mindset

I work at the tune shop at my local ski hill, and I've seen some new levels of kookiness this year. Last weekend some old lady came in with boots that had snapped in half so we sent her over to rental to get a full setup. She comes back with her skis from 1982 and asked us to set them up for the rental boots. We explained that we legally couldn't work on them and she was genuinely surprised.

I just don't understand why you would want to pay extra money to ski on your 40 year old skis when your boots that are the same age exploded from walking through the parking lot. What is going through these peoples heads?
