Mrs Waggett puts the tray on the left side of the screen, then, taking two cups with her, moves to the right of screen and that's where she stays when her husband finishes talking on the phone and, amazingly, the tray that was on the left side is now in her hands, without her moving to the left side to collect it.

He asks the manager "What are you doing, putting 45 in your own pocket?" as several not so reassuring individuals begin to crowd him.
