Mister Buckingham

Mister Buckingham is a Mr. Handy Robot and is owned by Vera Weatherly. He works at the Weatherly Hotel in Rivet City. He can be found at the front desk of the hotel, and can rent you a room. He also acts as the hotel's bartender.

Like all robots, he can be destroyed, this of course will make citizens hostile towards you, unless you can take him out in one shot while hidden. Interestingly enough however is that Mister Buckingham will respawn eventually, unlike any other killable named NPC. This maybe because that way there is always someone to rent a room from at the hotel.
