The man then squirted a liquid through a small hole in the office's protective glass, covering the front desk, floor and splashing on the clerk.
Moments later, after the clerk picked up the telephone, the man then used a cigarette lighter to ignite the liquid which quickly spread and burned the clerk as he backed away from the desk.
The clerk suffered minor injuries and is expected to be OK.
According to hotel management, that declined to talk with NBC 5 on-camera, the suspect had demanded the hotel guest list before lighting the fire.
