In Lisbon, before he sings the songs, MK says something like "Mr Brexit Man".
Maybe the character is old fashion and also a brexiter, because of that...
Yes, that's clear. That is not my point.

Mk always says that he preffer that people gets his own feeling about songs, not telling what they are about, but sometimes he says exactly what those songs are about, like in the case of "Bacon Roll". In my opinion that doesn't ruins the song but really adds something to it. If not you can think the song is about a random guy eating in a bar, the kind of character like MFN, but pointing to the old fashion man, the brexiter, it gives meaning to the whole thing, like "When you dealing with the toastie, what you prefer , brown or red", literally these are different sauces, but maybe the toastie is not a toastie, is the brexit thing, and the sauces are the choices... If MK doesn't explain such things, you can just understand the waiting is asking which sauce you want with the toastie...
Many songwriters doesn't want that the message is crystal clear when they write and record a song, and like that people gives it's own meaning, but maybe in the end they feel the song might need some explanation to get the meaning properly, specially when you are talking about toasties, that would be difficult to get for foreign listeners...
I hope i'm closer to your point now
