This exact thing happened to me while I was in self checkout at my local grocery store, and I found myself having the most awkward conversation about my life, goals, and this vague concept of "mentorship". I kept explaining that there are people I look up to and those people will give me advice on things, and I work for more reasons to make money, but the conversation was just very uncomfortable and bizarre.

It took me a while to put my experience in perspective, or even explain it, but after a while I found out there are several of these mentorship/get rich schemes roughly based around the ideas in "Rich Dad, Poor Dad" that involve basically recruiting strangers to form an MLM like downline. The basic pitch is: "If you had all the money in the world what would you do? [insert conversation here about what you'd do] We can give that to you if you follow us!". Obviously I'm not going to follow someone who fell for that!

Fortunately, I abruptly left this conversation mid-sentence because I was started to get freaked out by intrusiveness of it all. Very weird, and definitely an exploit on peoples willingness to be accommodating and friendly to strangers.
