There is a women who appears in the background of almost every episode with a radio booth scene. She is also shown frequently at Cafe Nervosa. She was also in almost every bar scene in Cheers. The only time you really see her front and center is in season 6's Roz a loan when Roz is saying hi to everyone in the hallway when they return to KCAL. She say's hi to everyone by name then says, "and you" to this woman. Does anyone know who she is? Thanks.
