Florent Neveur, who has run Creperie la Falaise with his mother for a decade, said it was all a misunderstanding, and claimed the British tourists were turned away because the cafe was full.

“Two buses came on Monday about 12.30pm, when it was a very busy time for us. I said, ‘Guys, I’m so sorry. I have to be focused on my restaurant, I can’t help you, I can’t leave my other customers’,” he told MailOnline.

“It gets crazy here. Sometimes we cannot serve everybody. I take care of my customers,” he said.

The Normandy tourism board swiftly reacted to the snowballing complaints, writing: “Morning Eugenie. Thanks for pointing this out to us. It’s utterly unbelievable. British visitors and soldiers will of course always be welcome here in Normandy, and the nearby British Normandy Memorial bears witness to the history we share.”

The cafe is located less than a mile away from the D-Day museum in Omaha and a short distance from the Overlord Museum and Normandy American Cemetery.

Omaha saw the Allies take the most casualties with around 2,400 American troops killed by German gunners and artillery on June 6, 1944, the first day of the effort to drive the Nazis out of France.
