If F/N owned the cars, and the drivers were actually employees of that company, then yes, of course they would have the right to make such an offer to the medical staff, or anyone else they like. But thats NOT the case is it ,? the drivers own the cars, the drivers ARE NOT employees, the drivers own their own businesses, yet the drivers allow 3rd party intervention in the running of THEIR business . That's like me saying to you big Dommo is a very generous bloke, he would give you MY last penny. If I lived to be a 1000 years old , I'll never understand the logic taxi drivers who are aligned to a dispatcher apply to their business
