A social media dispute erupted after a restaurant owner refused a customer’s request to have cheese put of a fish dish.

The customer took to the social media to complain that he was refused cheese, with the restaurant owner replying that it’s just not done.

The customer dragged the establishment with a scathing review on TripAdvisor, where he called the service "second to cow dung".

Owner of London's Maxio's Italian Bistro, Massimo Donato, was having none of it, however, and decided to teach the angry diner an important lesson.

The customer wrote: "Half way through the meal I felt like the dish needed a little something. So I asked the waiter for some Parmesan cheese and he sort of gave me a bewildered look.

"I waited for his response which I couldn't believe. He literally refused to give me the Parmesan, stating you do not put Parmesan on any seafood because it would take away the flavor."

The customer tried to convey that he liked his food "cheesy", but, not wanting to make a scene, he just ate his food and left.

It was when he was back at his hotel that he realised he need to "get it off his chest" so called the restaurant to complain. The restaurant stood firm on the issue.

In response to the review, he wrote: "No words about your rudeness and your silly request.

"NEVER ask for pineapple on pizza;

NEVER put cream on your Carbonara;

NEVER ask for any Alfredo pasta (who is Alfredo anyway?);

NEVER put chicken on arrabbiata;

And, last but not least, NEVER NEVER EVER ASK FOR CHEESE ON A FISH DISH. Simple rules as A, B, C."

He signed off with the burn, "Try parmesan on cow dung, it should taste fine for you."
