Chris Owen hates mayonnaise. And he says he makes about £90 a month by complaining about its unwanted use in food he orders at restaurants.

The 39-year-old PR director, from High Wycombe, Buckinghamshire, said he always tells staff when there's an issue with his food, and usually comes away with a free dish or a discount.

"The worst culprit is the burger - they always put mayonnaise on burgers," he said.

"Mayonnaise is a tyrant of a condiment, and very arrogant.

"It thinks it makes everything better but it does not."

Chris, dubbed "Britain's biggest moaner" by The Sun, said he prefers to be known as the best at not putting up with poor service and mistakes.

He told the BBC that he earns around £1,000 a year by sending mayonnaise-ridden food back after specifically requesting his food comes with "no may".
