Waiter (The Man from MI.5)

A waiter was part of the crew of the Fireflash flight in 1965 which took Lady Penelope Creighton-Ward from England to Nice so that she could meet with MI5 agent Jimmy Bondson. Towards the end of the journey, he was stood behind the bar in the cocktail lounge. (TV: The Man from MI.5)

Other sources dated the activities of International Rescue to the 1990s, (PROSE: The Dying Days) the 2060s, (PROSE: Titan Declares War! et al.) and the 2080s. (PROSE: Captain Scarlet in Death Crash! et al.)

Behind the scenes
The puppet which "played" the waiter was also seen in several other episodes of Thunderbirds. It had speaking roles as the Atalante Restaurant waiter in The Perils of Penelope where he was voiced by David Graham, as an engineer in End of the Road where he was again voiced by Graham, and as the speed merchant in The Impostors where he was voiced by Matt Zimmerman. The puppet appeared in a silent capacity as a train passenger in The Perils of Penelope, as the barman in Move – And You're Dead, and as a gambler in The Duchess Assignment.
