When I stopped working at the casino (just before moving to NZ), I thought the things I had to do there were gone--like 'clearing my hands' for the camera after I had touched somewhere that money could be.
To do this, you put down anything you are holding, put your hands up to shoulder height and spread all your fingers and show both sides of your hands to the camera. At any store, you could always tell who worked in a casino because we ALL did it when we put things back on a shelf.
Unfortunately, it became a habit that would take a while to stop doing. I would catch myself doing it even putting clothes away in drawers.
So, after all this time (12 years and counting) I can't believe that I just 'cleared my hands' so my cat could see that I don't have any more cheese!
The really funny part is that it seemed to satisfy him and he went back to taking a nap.
