A holoprogram of a massage facility
A massage facility was an establishment where one could go to get a massage. However, many such facilities also offered and provided sexual services.
Quark's bar had a holoprogram called Lauriento massage holoprogram 101A, which functioned as a holographic massage facility. It was used by a man named Ibudan, who was murdered by a man inside the holographic massage facility. (DS9: "A Man Alone")
Quark once expressed interest in opening an Argelian massage facility on Deep Space 9, although Elim Garak doubted that Commander Benjamin Sisko would approve such an establishment opening up on the Promenade. (DS9: "The Die is Cast")
