@Bobo_PK I remember that party vividly, the assembly I was with at the time was located between that toilet and Sendezenrum, next to the ppl with the blinking dildos that became part of the party decoration at some point. It went from someone keeping the door closed and letting people in/out, to keeping the door open, to the door being removed from the hinges and them just making sure it didn't get too full.

@Merovius Die Befestigungen am Schalter sehen für mich so aus als wäre dieser dafür gedacht auf/in eine Unterputzdose montiert zu werden, und nicht direkt in die nackte Wand.
