He's not become smarter.
He's now in the presence of an intelligent, knowledgeable professional who doesn't need to shout,or use big words, to try and impress DeliverRoo cyclists and UPD Parcel wallahs.
He's pretending not to be publicly affected by Stefans quiet demeanour and expertise.
However, since Stefans appearances, he's been quietly shifting his position for several weeks, as Stefan has been 'educating' him.
His favourite fall back quote now is... "I've been saying this for a long time"
The blokes an insincere charlatan who shouldn't be trusted with a cat.
Bravo Stefan !!
