Luke Littler threatened to boycott tournaments in the Netherlands after being booed and whistled at during his win over Nathan Aspinall at the World Series of Darts.
'The Nuke' moved a step closer to becoming the first man to win all 10 major televised tournaments in a calendar year, having triumphed in the first five, with a hard-fought win over Aspinall in Amsterdam.
Littler won the last two legs to prevail 10-9 but the match was overshadowed by the crowd's behaviour towards him.
The back-to-back world champion faced a hostile environment during Friday's win over home favourite Danny Noppert and it escalated on Saturday night as referee Charlie Costorphine had to intervene in the last-16 win over Aspinall.
Littler has taken a stance against volatile crowds before, refusing to travel to European Tour events in Germany as a result of his treatment from fans there.
And he is "100 per cent" prepared to do the same in the Netherlands.
"With the Germans, I haven't been for a long time, we will have to see in Dortmund whether it changes or stays the same," he told Online Darts.

"If the Dutch stay like this, then I'm not going to do any Euro tours over there. There's just no point in me travelling, wasting my time while I'm getting booed.
"I just want to play my darts, obviously sign autographs.
"The past two nights, I've done nothing, I've just walked off stage without thanking anybody. There's no point thanking everyone when they are booing me."
Earlier on Saturday, Gerwyn Price defeated Jim Long 10-5 and James Wade saw off Wessel Nijman 10-7.
Luke Humphries crashed out with 10-9 defeat to Dirk van Duijvenbode, in the afternoon session, while Josh Rock secured a 10-7 win over Ryan Searle and Ross Smith beat Daryl Gurney 10-5.
An emotional Van Duijvenbode, who was joined by young son Levi on stage after the match, said: "Having my kid here is the best thing in my life.
"I won this game because he was here. When you are playing against the world number two you are always nervous.
"When I looked up at him he made so happy every time. It made me so relaxed. In the end that is the reason I won it."
Gian van Veen prevailed 10-7 against Karel Sedlacek and now faces Van Duijvenbode in an all-Dutch quarter-final, while Jonny Clayton battled past Motomu Sakai 10-8 to set up his showdown with Littler.
The semi-finals and final will take place from 6pm on Sunday, following the quarter-finals in the afternoon.
