[Sundae]

When I worked for the NHS, the more professional GP surgeries would not see drug company reps.
And there was a big push in the PCT (Primary Care Trust) to get GPs prescribing generics. It was part of their incentive scheme, where the money went to the practice (for training, equipment, furniture etc) rather than simply a cash bonus for the GP.

We had varying degrees of success.

The smaller practices cried foul at every stage, the larger practices benefited.
But the small ones were usually one Doctor whose waiting room looked like his front room, with his wife as Practice Manager and his additional admin services provided by University-aged offspring on holiday and the cleaner was Auntie or Grandma.

They knew exactly how to work the system!
