Ronnie O'Sullivan stormed out of his first-round snooker World Open clash against Ross Muir after suffering a problem with his waistcoat.
The Rocket, 50, grew increasingly frustrated with a logo on his waistcoat, which was somehow disrupting his cueing.
And O'Sullivan shocked the crowd in Yushan, China, when he simply walked out on the match to go and sort his issue, causing a several-minute delay.
He had been fiddling with the badge, and when he stooped down to take a shot, he was clearly uncomfortable.
O'Sullivan bent over several times to try and line up a shot with the black, but on each occasion, he aborted the effort due to his discomfort.
The seven-time world champion did eventually re-emerge and went on to beat his Scottish opponent 5-1.
