Yes I understand that, I should have made it clear that I meant the crewmember dealing with the “celebrity”.
Now as a SCCM I really don’t know how I would have handled the conversation with the OPs father, would I have offered to move him back, probably not, I would have been very sympathetic and made sure he was given lots of attention. What I most certainty would have done is speak to the “celebrity” how strong a conversation would have depends on what I had been told by the father.
