There is a system in place at WDW that keeps track of all Guest complaints where any level of compensation was provided. When I am in Guest Services and I do something that is an "exception to policy" I have to make an entry in the tracking system with the name, address and phone number of the Guest, what the problem was, and what I did to compensate the Guest. I generates an "incident number" which I have to record in the transaction.
If a person comes up to us we can look them up in this system and see how often they get special actions taken. If the notes show they have been warned in the past I can either make a decision on the spot or call for a manager for further review and discussion with the Guest.
