Andy Carroll was called a "f***** c***" by an owner of a pizza restaurant, who left an angry note on his car.
It led to Calvin Kitchin leaving a note on his windshield, and he did not hold back.
In part of it, he claimed Carroll was "on a different planet to the working class" and doing "what you want, when you want".
In full, the note said: "Listen you rich f****** c***, you have a nice car I'll give you that. Otherwise I pay £42,000-a-year for my lease.
"If you were to come into my restaurant and ask if you could use my parking to park nicely, me or my staff would probably say yes.
"Otherwise, you are a c***.
"You don't understand the meaning of money and/or courtesy. You are on a different planet to the working class. You do what you want, when you want.
"Hence why you can't just be nice and take what you want."
Kitchin also went on to tell Chronicle Live about the ordeal, insisting Carroll had never even been in his restaurant.
He said: "What would be civilised is to come [inside] and ask if he could park his massive car, especially when there is plenty of on-street parking.
"He took up two spaces - what if a disabled customer came? There is a parking meter down the road which barely costs anything anyway."
Carroll responded to the note on Instagram, posting it on the social media site, captioned: "Didn't like your pizza anyway".
