No, I don't allow, because it could quickly turn into a "big mess" if every player has his own spectator

But every time I build the room layout, I think about spectators to make a rail as widest and closest as possible for the "show", without annoyance for the players.
And when a player bust, I allow him some minutes between tables (sometime to tell a friend he has bust or...) before asking him gently to leave the tournament area.
Firm in the rules and the room management, but allways kind and nice in my words
