Sometimes that's a tall order. While it's been changing (and sometimes to absurd lengths), historically AMP gals will choose from roughly 10 "American" names. My first AMP gal back in the 80's was named Coco. So, if a say, "Mimi" goes to another spa, the new spa may already have a "Mimi." It would get too confusing if you had "Mimi 1", " Mimi2." Kind of reminds me of the scene in Goodfellas with the "Paulies" and the "Maries."
