Fallout: The Bluegrass Wasteland
A reprogrammed Mister Handy
Maitre’D is a typical Mister Handy, with the addition of a chef’s hat and a pair of makeshift saddlebags.
The robot called Maitre’D used to be Postmaster Gray, the Mister Handy in charge of the Talcum town post office. He was successfully convinced to shut down and allow a factory reset by Del, who gave him a new name and set him to “American Butler” mode (which seems to be a sort of generic personality setting).
