Don't. That's my advice.

All joking aside, get the biggest split you can. If you are the only guy operating pinball, do a 80/20 split, not like he has any other options. Hell even tell him you want 100 percent of the drop but that he will make more money by having the games as an attraction and they will help keep bodies there longer.

I don't personally do contracts between locations and myself. If I decide a location isn't working for me I want to be able to pull it and not have to have stuff there for a contracted period of time.

Search around here there are quite a few good threads about operating. Feel free to reach out to any of the ops here like myself for help if you need it. I have found we are all very open to helping each other and discussing what is working and what isn't.
