In-Game things that people do that piss you off.

[Nightgunner5]

Non-security crew that do nothing all round except try stop antagonists and low level criminals.

HoS players and Security Officers that treat any criminal, no matter how trivial or insignificant, like they are griefers.

The best security guard will arrest the quartermaster who beat the traitor into crit instead of the traitor who tried to emag a maintenance door.
