So basically Trump, the owner and POTUS had a list of this he liked and wanted done, just like any famous musician who demands their dressing room have specific food, drinks, etc. before and after each show.
Any celebrity of any sort should be included in a green room discussion.. You don’t have to be a musician to be in a green room situation. Actors, big wig politicians, and other celebrities can very much desire to be catered to in the green room before interviews and such. As you mentioned, many of them have long lists of do’s and don’ts.
