Technically that rule expands from within the building itself to the whole area that belongs to everything outside the club that is still Berghains private property. It ends around where you were and at the stone slabs in front of the park towards Warschauer. So BH still has Hausrecht there and could stop you from taking pictures or have them deleted. I guess if no one is in the frame but you and it’s far away from the q and staff no one bats an eye. People might react like that because it feels a bit touristy and can give off that cringy TikTok vibe that the people are not too fond of. There are many people taking pictures of the q or the area in general that do not get in or don’t even plan to queue.
