Well, yeah, that’s exactly the point. From the opening post, I got the impression that their workplace was in some way hostile towards gaming, so I recommended a reference that would be easily recognized by an in-group (people who have watched some amount of Critical Role, which is probably the majority of D&D players at this point) and would come across as completely unrelated to gaming for anyone else. The fact that you, as someone who isn’t part of that in-group would have misinterpreted the reference means it’s working as intended.
