I've had a couple instances.
One of them, I was laid off due to covid, and knowing my old high school kept the football field cleared of snow I jumped in and went to blow off steam. Started throwing, and forgetting the school has cameras outside, a local By Law officer pulls up. Rolls down his window and goes "son, what in gods green earth are you doing?"
I simply replied "well, its kind of like playing fetch with myself, but with 25 discs instead of 1". He laughed, got out and we talked for a good hour about it. He left knowing more about disc golf, I left thinking "how did he not smell the liquor on my breath" (the liquor part is a joke, I promise)
The second one, me and a friend were throwing, see an old Oriental couple coming up the path so we stopped to let them by but they insisted we throw for them. I hit 400' for the first time, buddy throws his about the same, they look at us and go "who sponsor you?"
We laughed, said that we play for fun but they insisted we should go get sponsored. LOL. That was a feel good moment
