Holiday by Richard Christian Matheson (Twilight Zone, February 1982) starts with the narrator on holiday at a Bermudan beach when another tourist, a fat man with white hair and a rosy complexion, starts talking to him. After some chitchat the man says his name is Santa Claus. The narrator humours the man (who he thinks is a nut), and asks why he didn’t get an autographed photo of Joe DiMaggio when he was a kid. Claus mutters an excuse, and they briefly talk about other matters until Claus says he has an early flight to catch, and leaves.
This is okay I guess, but the ending isn’t really a surprise.
