Camping with a German mania for control

Camping with a German mania for control
We are there as a small youth group to celebrate in a small group. Since there are no slots, everyone parks as they are funny and the groundskeeper squeezes everyone close together. The hammer came on day 2 when the park security (who was previously unfriendly) came to see us in the water and said we should pay a 30 deposit as we could damage something (?!) The gentlemen also randomly had our funnel out of our tent and asked what we were going to do with it (?) Apart from the cheek to arbitrarily pay a bail to a group of young people although nothing had happened so far, like asking why the staff searched our tent while we were swimming.
The location is beautiful, the staff and service are unfortunate and the possibility of camping in such a small area is just about sufficient.
