The way to beat union thugs trying to muscle people out of the room is surprisingly simple—push pins. Purely defensive, you only poke what they are trying to push with. As needed, they can be hidden between the fingers. And if a cop is called, they can be tossed.
The thugs are at a disadvantage, because they are ordered to just push and shove, nothing more. If they get more forceful, don’t push, scratch.
Always try to keep them hidden, even when in use. And lose them at the end, in any event, because they are just push pins. Disposable.
you’re evil...I like that!
