If Lord Sugar said this instead for instance.

Azhar 'You are very lazy blah blah blah and all that he actually did say,(PLUS)' your business plan does not convince me.'

This has to be the reason for all the 'shock' firings this series. Instead of trying to plaster over the fact that he fired some people because of there business plan, he should just get it out there when he fires them, that he's not interested in the business plan. That would make the show a lot more credible.
