Quoted from rotordave:Then you’re buying yourself a free job for life.
Every time it breaks down, “oh he’ll come over and fix that for me!”
That’s not going to end well.

This is true. Just over ten years ago I helped an acquaintance with a game repair. It wasn't a big deal and the repair was minor. He had another problem a few months after that and it was more complex and took up nearly an hour to diagnose and fix. I had asked him to buy a manual the first time I came over and after the second repair--which would have been easier had a manual and schematic been on site, I told him that until he starts to help himself and me by buying a manual, that I wouldn't come over and fix the game again. Both repairs were no charge. Fast forward eight years and it is the middle of December and he texts me asking to fix his game as he has people coming over for the holidays. Haven't heard from him in all that time. I asked him if he bought a manual, and he answers no so I give him the names of a couple of techs in the area that might be able to fix the game. Manual available or not, I wasn't going back over to fix his game. I still do repairs for friends all the time and don't mind doing it, but as in the above example, you just have to realize when someone is simply taking advantage of you being helpful.
I think in the OPs example, I would treat it as a business transaction and leave it at that.
