Thread drift warning -
I give demo flights for a glider club close to home. While we're doing the pre flight paperwork I'll ask what brought them out to the club. Maybe they just want to say they've been in a glider. They could want to learn to fly in a glider. Maybe they're a power pilot looking to do an add on. There is a different level of engagement for each group of people. Is it that hard to ask one question?
