If you think about it, Durrant has an incredibly easy yobb. He only has one thing he has to do - and that is to keep Black Horse chasing their losses and funding the company so Durrant can keep pulling the salary, benefits, expenses, and free travel.
When the munny runs low, he just has to do another song and dance routine for Black Horse and gett them to 'pony-up' more munny to chase their sunk costs.
The rest of the time - is rest.
