My experience of KitKat is that unwanted attention of any kind (which depending on the night might not be super rare) is quickly shut down by the people in the immediate area before the staff even get close, and then the staff respond very quickly to it, especially if someone who is a regular calls attention.
The scene is prone to issues and what we do in my town is not allowing new people unless they have a fet account and/or accompanied by a regular. There's also a blacklist of known offenders. Not sure if that's the case over there.
I really hope I can visit it one day but I'm really afraid of travelling all the way there and being refused..
Ps regarding Lindemann I'm not a big fan of cancelling people before the facts come out. I absolutely abhor abuse but I'm also very much in favour of innocent until proven guilty.
It wouldn't really be a risk of him misbehaving because there's so many eyes on him. But I know it's a tough line to draw. Glad I'm not a club manager.
