...And Cut! is a film-related store in Grand Theft Auto: San Andreas. It has a branch located in Market, Los Santos, San Andreas. The store logo has its words stylized within the frames of a film reel. It is obviously a reference of the movie directors saying this after an outlet.
This store may actually be based off 'And Cut! Video Services' in real life Los Angeles. More on this service: http://www.andcut.com/
