Bernard Tomic has reportedly apologised after clashing with staff at a Gold Coast resort over a $20 court hire fee.

A member of Gold Coast RACV Royal Pines said the world No.18 asked local players to leave the court which prompted them to complain to the resort's general manager of sports.

Tomic was then asked by the manager to pay the $20 court hire fee, sparking an outburst from the 23-year-old.

"I've been so focused on preparing for all my matches, I know there's no excuse for my behaviour," Tomic told News Corp Australia.
