After starting to work, I knew several people who had problems getting up to go to work. After watching the Judy Holliday movie Bells Are Ringing, I was inspired to offer my services to call people to waken them! The business in the movie was named "Susannahphone"; I called mine "SUZYPHONE"!
When I asked my clientele why they didn't just use an alarm clock, they all invariably responded that it was very easy to turn off a ringing clock but they had to physically arise to answer the telephone. I was astounded that the people would actually pay me to call them!
I maintain a list of the OLDEST LIES IN THE WORLD which contains excuses people use, and one person actually used the excuse that "Sue didn't call me" as his reason for being absent. I reminded him that he had not paid his bill for two weeks and that I had had to discontinue my "service"!
Years later when I was in management, I would call people who had not called in as absent; nearly always they had just overslept. I heard one of my favorite people, Diana, tell others, "There's nothing worse than hearing Sue say "Good morning!" and you know you've overslept!"
