It is being called at 9am after you finished work at 6am to come into work at 4pm. Yes, this happens.
And remind me again why you would even answer your phone in this situation. Surely you would be sleeping with your phone off or on silent. Surely if it was a work number you wouldn't answer it because you are asleep!
Come on - most of the controllers love the OT otherwise they would be 'asleep'.
