The whole NY calling hatzala for every scratch attitude is pretty absurd.
Where I come from, if you break an arm, you drive to the hospital with your other arm. If you need stitches, you drive to the hospital. You call an ambulance when you need care faster than you can get to a hospital yourself.
When you call Hatzala, you are often taking a father away from his children, a husband away from his wife, a kollel guy away from learning, a person away from his job. Yes, they are happy to come- but don’t do it unless it really is an emergency.
