Stanley can most often be found playing Poker in the Blackwatersaloon or in the Blackwater Hotel at the High Stakes Poker table. He appears to own or work at the Blackwater Theatre, as he can be seen manning the ticket booth.
Stanley sometimes mentions a "Hollingsworth" while playing poker. He could be referring to Earl Hollingsworth, a Marshal based in Blackwater.
Stanley cannot leave the theatre. If he runs away, he will soon reappear behind the booth.
Stanley is one of few characters in the game to wear glasses.
When walking into the High Stakes poker room in the hotel, Stanley appears to have a larger chance of appearing than the other players; he is almost always there.
Amusingly, if Stanley is the last player to be busted after Marston wins, he will leave the hotel and may walk near the theatre, where another Stanley Palmer is working the booth. They may also converse.
