Question: When Walt Disney created the Disney theme park in the 1950s, he forbid its actors playing characters, such as Mickey Mouse and dog Pluto, which were meeting and greeting the public in person, to talk. Mr. Disney thought it would be too difficult to control the service encounters between customers and the Disney characters, and it would ruin the "magic" of Disney. Therefore, Disney characters (actors) were trained to gesture and use only their body language to interact with and entertain guests. Today, Disney is experimenting with using talking characters.

List some advantages and disadvantages of using talking Disney characters from a service design perspective.
