Last call

I was sitting in Sydney Airport patiently waiting to board my plane when an announcement along the lines of
"This is the last call for Qantas flight xx. Would Mr Zhu Ming please make your way to gate 33 immediately. "
boomed over the loud speakers. As this was repeated in various ways over about a 20 minute period, it became quite plain that this poor man was having an identity crisis and he was not zooming at all!!
