The Lollipop Lady

We were discussing the roll of the lollipop woman ( school crossing patrol officer). The community police officer was in dealing with another class. I sent two children along to ask him the question they didn't know the answer too.
"Does a car have to stop for a lollypop lady by law?"

So off two children trotted.

" Miss, does by law mean it comes from the King or Queen?"

me "It means they come from the government."

" what's government? Is that that man that wears a towel on his head?"

I was still sitting with my mouth open trying to make sense of that when the two questioners returned.

" Yes, if the driver doesn't stop, they can be charged. I think it will be about £100."

I am still trying to figure out the towel on the head crack.
