A while back a buddy who is an EMT told me about a 'frequent flyer". He lives near the hostpital, is a career alcoholic/unemployed mooch/one of the guys you see standing on traffic islands with a sign.
When he is away from home and wants a free ride, he calls 911 complaining of chest pains. Of course, they have to go and get him. He gets out of the ambulance, waves bye, and half the time doesn't even go into the ER, saying it was gas, he feels fine now.
And of course, the one time the EMTs will be slow to respond will be the time he drops dead of a heart attack and his family sues because it took too long to come help him.
Should do it like it used to be, you pay to ride - either a fee for services rendered or a yearly subscription/membership. But of course, these people are entitled to free rides, it's one of their rights because they pay taxes.
