If I were you, I wouldn't say anything since it isn't your business. It's actually rude. I know you are trying to advocate good financial behavior but there are other ways to do this and financial advisors are providing a service, albeit expensive, it is legitimate service and not a scam. Car dealers, time share salesmen, and whole-life policy sellers are arguably much worse. Just enjoy your free red lobster/olive garden/outback dinner and take it all in.
But either way, I'll be interested to see how it goes.
