Having privacy and selling maple syrup / putting out a donation box don’t seem compatible to me. What am I missing?

Maybe they could put up a sign to clarify what is permitted and what is not at their place of business? It might not be obvious since so many ice cream businesses encourage people to use their property, picnic tables, outdoor furniture, and/or lawn.

I’ve also witnessed tourists walking across lawns of private residences for photo ops which I find shocking and rude.
