Joe Cullen was left bemused at the German fans during this weekend's latest
European Tour, the
German Darts Championship.
Some spectators regularly whistled when The Rockstar was throwing and did it throughout the weekend which prompted George Noble to threaten to call a halt to the match.
It didn't go that far but Cullen lost the game 6-3 to Gurney. Afterwards 'The Rockstar' took to Twitter to show his frustrations.
"Why would people come to darts to whistle to try deliberately put someone off? Always loved playing in Germany and this is an isolated incident, but you absolute helmets!! No need at all!! Especially when the game is in the balance, stay at home next time," he said.
"Booing in unison is fine - the one or two idiots that whistle when going for a double (for both players) are just out to cause annoyance," he added.
