OK, my take is that he's "brexit man" also known as a Gammon here in the UK, a white man, 50+.
He's a pain on the arse and he's been let go from his job because he's a pain in the arse.
He's in the cafe, and he's on his own, but he's trying to engage another customer in conversation, telling them about his old job.
In between he's haranguing the waiting staff, asking where his food is. He's alone so he's trying to get the person to join them so he says he could get them a toastie.
Haven't actually heard it yet...
