Ronnie O’Sullivan asked referee Desislava Bozhilova to “chill” during the final session of his quarter-final against Stuart Bingham after he refused to come to the table while fans watching the match on the other side of the arena trickled in.
Fast forward to the 21st frame and O’Sullivan again appeared to take exception with Bozhilova’s handling of proceedings.
With the tussle between Kyren Wilson and John Higgins about to resume after the mid-session interval, fans had started to return as O’Sullivan sized up an important red following a Bingham miss.
The pair were locked at 10-10, so rather than rush the shot or take it on amid all the background noise, O’Sullivan went back to his chair as Bozhilova urged the spectators to return to their seats quickly.
“Would you take your seats quickly, and then hold the door closed for a minute,” Bozhilova said, while Dominic Dale and Phil Yates agreed on commentary for Eurosport that O’Sullivan was “doing exactly the right thing”.
Satisfied, Bozhilova then gestured to O’Sullivan to come back to the table, but the seven-time world champion remained unconvinced.
“But we might wait 20 minutes,” Bozhilova said.
“I’m chilled,” the referee insisted.
O’Sullivan then got to his feet and duly slotted the red into the top-right corner, although he would go on to miss a simple red and lose the frame to fall 11-10 behind, eventually losing the match 13-10.
