Ambulance

This was a first. I pulled over, as you would when you see an ambulance with its lights on coming toward you.  Why?  Because an ambulance was speeding towards me.  Anyway, I could see that there were two EMT's in the truck, one of them driving the ambulance.  I could also see them playing rock-paper-scissors (rochambeau).  I witnessed THREE games.  It really made me wonder what assignment the winner was hoping to avoid when the ambulance reached the destination.  Thoughts?
