At Park Royal in West Vancouver the other day, I offered to hold the elevator door for a group of the most lovely, well-behaved children I had seen in ages.  Their three teachers graciously declined my assistance, saying that their safety protocol was to hold the door themselves.  Very impressive.  Hmmm.  Polite uniformed children, good behaviour and professional adults.  They had to be..  Yes..  When I asked – all was confirmed.  They were from CEFA.
