I was in the supermarket today, and while walking past the checkout
counter, I got zapped in the face with the laser.  Does anyone know
if this is unsafe?  The first thing that I learned about lasers was
never to shine one in someones eyes. (The second was that laser tubes
retain a charge after they are unplugged, but that is a different 
story :-}  The tube looked like it was about a 5 mW unit. Any idea
what to do about this (other than wearing blue sunglasses)
