I like how you chose to experience a snack that is on the more creative end of the spectrum! It definitely gives a different view on how snacks can be experienced.
I wish you had planned a little more ahead with the interview. It was lucky that the girls were in the store when you were, but if there hadn’t been any customers you would have run into a problem. Since they were minors, you probably should have gotten their parents’ permission as well.
What if you talked to your mentor’s son? It would be interesting to get the perspective of both parties involved and compare them!
