Especially the last task.
He usually points out the faults of each candidate before, the pause, then naming the person to be fired . With the Rubbish task it became silly and farcical.
He pointed out each of their faults then I thought Susan was for the chop when he paused at Susan with the tone of voice 'Susan' Susan winced "but Susan I'm giving you another chance" then I thought Zoe was definitely for it "but I've concluded Zoe you did lose it, pause, however Edna etc"

I don't mind a bit of tension but don't over-egg it.

I thought it just showed that he was more unsure than usual about who to fire, and that it could conceivably have been any of the three as they all screwed up in some way.

If he did it every week, then it might bother me, but generally the choice of who to fire is a lot more obvious.

He knows pretty much from the start who he would or wouldn't go into business with, it is just a TV show and a good one at that. Personally the way they carry on and the lack of any sort of ability I wouldn't take any of them on. They may be academically bright but when it comes to hands on skills most of them havn't got a clue.
