Your comment instituted a tongue & cheek low bar for low jail threshold, I just went with it. These days you need to practically murder someone to finally get sent to jail (at least where I live). But if someone physically barred me from entering a fast food restaurant, I’m not sure why that wouldn’t at least be assault (assuming I tried to force myself in, of course then the question is who is assaulting who, that can get messy legally). But, no, you wouldn’t even go to jail for assault, or would get bailed out quickly and get let off by the judge.
Well if someone barred you from entering a fast food that would be assault, absolutely.
But what if someone was pretending to be a public worker doing sidewalk maintenance and that forced you to simply walk on the other side of the road and not being able to access the fast food?
That to me is more like an annoyance and a form of protest.
