It was an event labelled [A-RP]. You’re not being “deprived” of an RP opportunity - you’re actively being a disruption by essentially stating:
This sign can’t stop me, because I can’t read!
It was taken to OOC because you actively ignored the wants of the event organizer. You have the right to roleplay as you see fit but it’s also incredibly poor form to decide that your desire for roleplay is greater than the efforts put into by the people setting it up. You get me?
