Job Alert: How Would You Like to Babysit Robots?

Book a night at LAX's Residence Inn and you may be fortunate enough to meet an employee named Wally. His gig is relatively pedestrian--bring you room service, navigate around the hotel's clientele in the lobby and halls--but Wally's life is far more difficult than it seems. If you put a tray out in front of your door, for instance, he can't get to you. If a cart is blocking the hall, he can't push it out of the way. But fortunately for Wally, whenever he gets into a spot of trouble, he can call out for help.
