German Ironman triathlete Jaroslav Bobrowski, 30, was banned from the all-you-can-eat Running Sushi in Landshut, Germany.

The ban came after the restaurant's owner said Bobrowski ate five people's worth of food in one night.

Bobrowski was a regular at the sushi spot, but the owner saw his last meal, in which he had 100 plates of sushi, as "not normal."

An Ironman triathlete in Germany was banned from an all-you-can-eat sushi restaurant in Germany after the restaurant said he ate too much.

Jaroslav Bobrowski, 30, paid just 15.90 euros ($18.49) for the all-you-can eat meal at Running Sushi in Landshut.

But the owner banned him from the restaurant after he says the athlete ate five people's worth of food, German website Passauer Neue Presse reported.

Bobrowski was a regular at the sushi spot, but the owner said his most recent meal, in which he had 100 plates of sushi, was "not normal."

TripAdvisor shows that Running Sushi provides about two or three pieces of sushi on each plate.

The restaurant primarily makes the money from alcohol on all-you-can-eat nights, but Bobrowski stuck to tea while eating his big meal, according to Eater.

Bobrowski, who is a software engineer when he's not competing as an athlete, is on a special diet where he fasts for 20 hours then eats until he is full, The Local reported.

Bobrowski said he was "stunned" when he learned he was banned.

"When I went to the checkout, I wanted to tip, but the waiter did not want to accept that," he recalled of the incident.

Instead, the owner and chef told him he was banned for "eating too much."
