King made the 2009 PDC World Championship semis
Mervyn King has hit out at the growing culture of booing players while they are at the oche as he prepares for his opening PDC World Championship match.
King, 44, believes an increasing number of non-darts fans are stepping over the line with their vocal interaction.
He told BBC Radio Norfolk: "I'm up there to do a job, I'm not there to have a jolly with the crowd.
"It's my living. I don't turn up at their work and boo in their ears for eight hours, do I?"
The 2009 semi-finalist, from Bradwell in Norfolk, has defended supporters who come to appreciate top quality darts and hopes vocal spectators keep within the spirit of the game at Alexandra Palace.
He added: "The actual darts fans are fine, it's the others that turn up and get drunk and show no respect to anybody or anything in the venue.
I'm now starting to get my head around the game a little bit. But there's a lot more to life than darts
"They're turning up with a football crowd scenario, they're not really darts fans, the true darts fans will give respect to the players.
"It's OK having your favourite, but show some respect when the players are at the board.
"It's not just unfair, it's downright out of order. But the mentality of people - it says a lot about them really."
King will face either Magnus Caris or Dietmar Burger in the first round on Thursday, with his opponent decided earlier the same day.
But the world number six admits he will also have to overcome the emotion of losing his father, who died earlier this year.
"It's not been the greatest pre-tournament regime. I'm now starting to get my head around the game a little bit," he said.
"But there's a lot more to life than darts."
