My neck hurts, I tend to nod these days.
But from memory, last time I was at YYWG I didn't see any intimidating signs, but if I had, it is my usual habit of ignoring them anyway.
It's usually the people that put them up who have the problem, and the sign is simply an attempt at "problem transferrence" which people should transfer back to the person with the original problem.
Don't you people see, it's people who are the problem, not me?
