I like the emphasis on privacy. I have seen too much recent invasion of privacy. And, many years ago, I worked for a chain of retail stores with over 200 locations. I foresaw a problem, and over the PA system I would call (examples of made up names) "Jane in Jewelry" or "Sam in Sporting Goods" or "Ella in Electronics" "Peter in Pharmacy," as a few examples. Most of the other folks who worked there would call, Jane Jones, or Sam Smith, or Ella Edwards, or Peter Pipe or whatever.
One day a lady in a particular department started getting phone calls at home. (This was WAY before cell phones became common or inexpensive; if you are paying $2.00 a minute for air time, you tend to think several times before buying a cell.) These harassing calls caused her to get the phone company to change her number. The caller had put the first and last name together and looked her up....
Someone at another location was attacked at home by a stalker. With the number of nuts in the world now, @quokka is right to emphasize privacy, in my opinion.
