First data credit card company.I worked in one of their buildings for a year and saw several of the people that were in the call center that had ankle bracelets.These were the people that had your credit card numbers and you called them when there was a problem.Every few days an employee would be told that they were getting an award for outstanding service and to go up to a certain room.Once in the room the doors would lock and the cops would escort them out another door.
