I had to call 911 on Thursday--a car in front of me on the freeway ran another car off the road and it went spinning off into the trees. Thankfully, they picked up after one ring. Usually if anyone's going to put you on hold, they first pick up and say "May I put you on hold?" I would've screamed "NO!!" and just started talking.
I felt especially horrible when I heard the story of the little boy who called 911 for his mom and the operator chided him for "playing with the phone" and hung up. His mom died.
