Morris P. Grout

From Multiversal Omnipedia

Morris P. Grout was the fussy manager of the Sedgewick Hotel, and one of the few people on staff who knew the full history of the disturbances occurring on the twelfth floor of the building. But after some newlyweds complained to him about a foul-smelling ghost in their bathroom, Grout called the Ghostbusters, pressing that they handle things "quickly and quietly, tonight." Despite Ray Stantz's assurances, the Ghostbusters ended up causing mass destruction throughout the hotel, to the point that when they finally caught the offending spook Grout initially refused to pay the $5,000 bill. However, he relented after Peter Venkman threatened to "put (the ghost) right back."
