'It's nonsense!' - Judd Trump ball-placement incident prompts frustration
An agonising wait of nearly five minutes ensued as both Trump and Ford watched on perplexed and frustrated, while Eurosport commentator Neal Foulds made his agitation known.
"Listen, you don't want to start me off on how this isn't the way to do it, surely," Foulds said on Eurosport commentary.
I mean, it's ludicrous that this is having to go on with a marker and a referee. This is like something from about 30 years ago, isn't it?

"This is an example of how to make something that could be sorted out in 20 seconds, last five minutes.
"Come on guys, get on with it! I think we should just be playing."

Trump looked visibly frustrated by the exchange and repeatedly muttered: "No. It's not right, I don't think it's right."
Thankfully, when the officials finally did get there with the ball placements, Trump found the red he needed at the second attempt to ensure everyone did not have to go through the whole thing again.
