Neil Robertson booked his place in the Scottish Open semi-finals with an impressive 5-2 victory over Mark Selby, but not before he apologised for mistakenly sitting in his opponent's seat.
Robertson has hit a purple patch of form at the Edinburgh tournament and won the opening frame with a huge break of 133. After potting the opening ball of the second frame the Australian returned his seat as Selby returned to the table.
After spending so long at the table the world number four briefly forgot where he was supposed to be seated taking Selby's chair instead of his own.
