The Guide was a character from the artificial reality game Better Than Life.
The Guide was designed to help players navigate their way through the game. The Guide was dressed like a waiter, in a garish red shirt and jacket. He carried a clipboard with "Better Than Life" written on it.
When Rimmer, Lister and The Cat entered the game, The Guide was there to meet them. He told them about the restaurant 2 miles away and that they could get there any way they could imagine.
He then met them at the restaurant, acting as Maitre d' and waiter. He served Lister with his Caviar Vindaloo and brought The Cat a small aquarium full of live fish - and a fishing rod.
Later, when Lister was thirsty while playing golf, The Guide was immediately there to provide him with a large, garish cocktail called a banana bomb. He lit the firework in the glass and watched it fly into the air. (Better Than Life, Series II)
