For me, the biggest complaint is when the presenter says, 'I’ll do my very best/I’ll use every trick I know to get this property on budget for you.'
And this is what happens.
Presenter: How much would you like to offer?
Presenter: Ok, here goes.
On phone: Carlos? They’d like to offer £75,000
Presenter: Let’s see if that works.
Presenter: ok, uh huh, I’ll talk to them
Presenter: He says that they’ve rejected your offer. Would you like to bid some more?
Presenter: ok, well I hope you do well in the future.
