I got this from a friend:

     Outside England ’s Bristol Zoo there is a parking lot
     for 150 cars and 8 buses. For 25 years, its
     parking fees were managed by a very pleasant
     attendant. The fees were �1 ticket for cars ($1.40),
     �5 tickets for busses (about $7).
     Then, one day, after 25 solid years of never missing
     a day of work, he just didn’t show up; so the Zoo
     Management called the City Council and asked them
     to send another parking agent.
     The Council did some research and replied that the
     parking lot was the Zoo’s own responsibility.
     The Zoo advised the Council that the attendant was
     a City employee.
     The City Council responded that the lot attendant
     had never been on the City payroll.
     Meanwhile, sitting in his villa somewhere on the coast of Spain
     (or some such scenario), is a man who apparently had a
     ticket machine installed completely on his own; and then
     simply showed up every day, commencing
     to collect and keep the parking fees, estimated at about
     $560 per day — for 25 years.
     Assuming 7 days a week, this amounts to just over
     $7 million dollars!

     ….

     And no one even knows his name.
