It seems the partridge esque persona is totally fake though, compare it to his earlier reviews, never acts the prat there. you could argue its because he was nervous or what have you but even when he seemed to have built up some confidence a year or so in he never acted this much of a pleb. Again questioning whether Danny is the influence or if its their agency.
And its been some time since he came out with the whole 'i dont get paid for reviews' response to accusation videos etc so that mightve changed by now, especially with Danny being the sort of reviewer/ creator that would literally wear sponsors on a t shirt. On the other hand not getting paid just means he can be as rude or have as many bad takes about the food / places he wants, he wouldnt be able to do nearly as much of the click bait slop if he had to promote every place with one of his favourite bits being 'it isnt worth it for the money'
he probably just wants to be associated with them as much as possible given they're both good at what they do in the restaurants and on socials
