Nathan Aspinall stopped his celebrations after beating Dirk van Duijvenbode to confront the marker on stage twice before the referee stepped in.
The German Darts Grand Prix features some of the best players in the world and Sunday saw the likes of Luke Humphries, Michael van Gerwen and Michael Smith all progress to the next round.
Aspinall was the last match of the afternoon session to get underway and he got off to a slow start against Van Duijvenbode.
The Dutchman raced to a 4-1 lead and was just two legs away from knocking Aspinall out.

Van Duijvenbode missed a great chance to make it 5-1 and Aspinall took full advantage to level things back up.
Aspinall went on to win the next five legs to wrap up an impressive win and progress to the third round.
But something appeared to annoy Aspinall during the match as he went over to the marker to explain his frustrations.
Aspinall waved his arms around in a writing gesture with suggestions he was unhappy about the speed of the young marker.
The Premier League star walked away to shake the hands of the others on stage before running over to return to the marker again.
There didn't appear to be any real malice in the exchange as Aspinall smiled with the marker, however referee Huw Ware felt necessary to step in and separate them.
The victory saw Aspinall set up a testing clash with compatriot Ross Smith, who entered the tournament as the 12th seed.
There were a few upsets in the second round though with the likes of Stephen Bunting and Ricardo Pietreczko being knocked out.

Humphries appears to be the man to beat though as he's averaged 108 and 111 in progressing to the quarter-finals.
Speaking after his second-round win against Luke Woodhouse, Humphries revealed his confidence about going all the way in Munich.
“Luke is a fantastic player. I knew I had a tough task tonight,'' Humphries said.
