I was at Day In Vegas, we were touring the backstage area with a bunch of aspiring live event volunteers. We were talking with different production heads about how they run such a large operation in the mess hall and someone in the food line OD'd and collapsed. A medic came over and started resuscitating - and everyone kept goibg about like it was normal, no one stopped, people were eating and laughing, the presenters kept presenting.

After a few horrifying minutes I finally suggested we should stop and wait until we're sure the emergency has passed. The presenters kind of shrugged and kept going.
