Cheery room service robot surprises guest

A hotel guest in Newark, California, was given room service with a difference on Wednesday 4 March when a robot came to his room. Scott Sigrist opened his door, at the Aloft Silicon Valley Hotel, to find a cheery robot delivering him toothpaste and a fresh towel before making its way back to the lobby. Staff told him it could deliver any room service items to him -- and said he should watch what happens when he rates it five stars.
