Common Senslessness

This morning I got some coffee from the school cafeteria.  I put the coffee into a mug that I had brought with me- a ceramic mug from home.  One of the cafeteria ladies immediately came over to me, and told me with serious gravity that I couldn’t do that.  Federal law requires me to waste a cup and pour my coffee into a plastic cup   What distrubs me deeply about this incident is that the woman didn’t seem to realize at all how ridiculously lacking in common sense this statement was.  She just stared at me like she was saying something of actual importance.  The idea of questioning the absurdity of federal regulations or utilizing common sense was not running around her head. 

When this happens in humans, it scares me. A lot.
