My guess is that being a 911 operator is far from "boring".
I think 911 operators deal with life-or-death situations.
I know on those few occassions when I have had to call 911, it has been because someone was having what I thought was a "medical emergency". (One time, for instance, was when a diabetic associate at work was acting as though he either had too much or too little sugar in his system).
911 operators, I think, must first calm the callers down (I know I was agitated when I called 911, and the first thing the operators have always done is to tell me to calm down). Then they must get enough information to know what to do.
Being a 911 operator is, I would guess, a high-stress occupation.
It wasn't too long ago that there was a news story about a 911 operator who spoke to a little girl who had just been awakened by gunshots and had seen her dead parents -- with blood coming from her dad's mouth. The way the 911 operator handled that called and calmed that little girl convinced me that 911 operators do not have boring jobs.
Did you listen to the actual call of the mom? She doesn't sound very serious, therefore the operator didn't really take her seriously. I have also used 911, one time, because my lawnmower caught on fire and got the grass burning, too. The fire department was at my home in less than 5 minutes and put the fire out, which had spread very quickly. (I live on acreage) My point is, the operator knew I wasn't kidding since I was darn near panicking and acted accordingly. If I was halfway giggling during the call, I wouldn't expect her to take me too seriously.
