Alternatives to lunch meetings

[Brandon Rich]

Hey all, I'm reading the book on rental property investments, and I've identified a few people in my circle who are in this business.  Normally, I'd offer to buy them lunch so we could chat a bit about their experience.  Outdoor dining was an option until the weather turned too cold recently.  I know these folks well enough they may just agree to a half hour phone call, but if I'm going to pepper them with questions, any suggestions on what I could offer when I ask for a meeting?
