You are a person with judgment. Judging is not only allowed, it is required.

When I was in my clinic I shushed a nurse who was positively howling at their phone in the middle of the night when a) people were sleeping but I was up, pacing) and b) we patients weren't allowed phones... Turned out they were on *camera* phone so I turned them in for horrible HIPAA (the P is Privacy) violation. Boy did they get in trouble.
