Sorry for being cynical, but he obs had money about him with the stuff he bought, hes knowledge was lacking (something you can improve) but he saw it as a business opportunity
If you look back at previous videos you will see hes done seminars on sales, business and marketing strategies etc, hence the gift of the gab.
Imo what he does is a million miles away from the polished stuff on YouTube, which is why so many channels have massive cunt followings
As dfk said with the cremina grinder people bought a £1300 grinder on his say so, and it was a terrible grinder by all accounts, even lance called him out on that.
I take pretty much every thing now as advertising, hell dont even listen to me, i can only give opinions but happy to show people given the choice
