Jon Coffee is now Give me Coffee or give me Death- Good Omens
From Michael Ralph (season 1): “We called it 'Jon Coffee' after John Coffey in The Green Mile because I've always loved that. Don't wanna get sued for that, but I spelled it with a J-O-N, not a J-O-H-N.”
Coincidentally or not, the initials of John Coffey stand for Jesus Christ. He represents the new Messiah, someone sent to us two thousand years after by Mighty God. (Which, although the name of the shop was changed, it was very much in line with The Second Coming).
Now we know the coffee shop as Give Me coffee or give me Death, a reference to Patrick Henry.
