Louie is the bartender at Taffey Lewis's club. Louie is only seen in the scene where Rick Deckard briefly interviews Taffey. When Taffey is uncooperative, Deckard asks Taffey if his licenses are in order, and Taffey brushes the threat off by telling Louie to give Deckard a free drink.
He was played in an uncredited role by Leo Gorcey Jr.
In a deleted scene that didn't make any of the official cuts (but can be viewed in several of the fan made cuts of the movie), Louie has a slightly bigger role with some dialogue. After being told off by Taffey Lewis, Deckard is told by Louie that if he wants to know about the snakes, he should check with the dancers back stage.
