I made this mistake with “Ruffles” - a chocolate-covered coconut snack.
I mentioned I liked them, and for the next year or two, every week my grandpa would stop by to give us 2-3 boxes of ruffles. We had a cupboard literally full of them, we were giving them away, and I ate so many that the thought of them makes me feel queasy now. We kept telling him to stop, but the man was on a mission.
Sadly, he passed away last year, and I made sure to bring a couple boxes of Ruffles to the service.
