The MasterChef semi-finalists were cooking in John Torode's old haunt Bluebird, a dining hotspot in Chelsea since the late 90s.
They created their own dishes for a bunch of pro-chefs in the 'MasterChef pop-up', with John running the pass in the kitchen (that means being in charge of telling the orders to the chefs, in restaurant speak).
And boy, did he get stressed out.

He was shouting, complaining and throwing lots of shade whenever he didn't get a 'yes chef' or if anyone DARED show any signs of (completely understandable) pressure.
Viewers thought he was being unnecessarily mean.
John is such a daddy in the kitchen
shouting at them, getting them there.
hello? Yes chef! #MasterChefUK

And getting himself into a right flap when this is a pretty normal environment for him.

Torode is bellowing like a foodie Minotaur, lost inside a pop up labyrinth #MasterChefUK

C'mon John, maybe a bit of a reality check is in order.
