On the EMS flight, it was.   It was a flight being requested not by the Nurse/Medic, but by a customer looking for an EMS helicopter to perform an air ambulance flight, which was cancelled because a medical crewmember had the final authority here say NO.  

The other situation was a private customer looking to move an employee of a that private customer.   It a flight being offered to the public as an AIR MOBILE MECHANIC SERVICE.

The one is a non-common carrier flight, the other is a common carrier flight!

The public was calling for an air ambulance and some non-pilot was making an operational decision not GO/accept the flight based personal feelings/comfort levels, even after the PIC (who has final authority) accepted the flight (i.e, said GO).
