Over time all three of my kids ran a stand at a nearby corner next to the main north-south drag through our town (bumper to bumper during RH) with a sign reading “Free Lemonade! Donations Accepted”. They made out like bandits.
When we were kids, my siblings and I used to make our own root beer and lemonade, and mix frozen orange juice.
We then hauled our table and chairs across the highway to the lake, and sold product for 2-4 hours each, or until the product for that day was all gone.
This worked fine for 2 years, until the Kiwanis Club decided we were doing too well, and they built a concession stand where we used to set up.
That stand has been opened about 10 times over the last 36 years, but they did manage to boot our little tushes off “their” turf...
Regulation, it has NOTHING to do with safety, and EVERYTHING to do with CONTROL!
