Nothing is certain in life apart from death, taxes and golfers moaning about pace of play.
Over at GolfMagic we are racking our brains to think of a time where a tour pro has called out slow players during a tournament round.
Mike Lorenzo-Vera just might be the first. He's a French golfer who plies his trade on the European-based DP World Tour.
The name might ring a bell as the Frenchman, 38, has hit the headlines over the past few years in men's professional golf.
Primarily, the golfer has put LIV Golf and 'rebel' players firmly in his crosshairs.
This time, though, it appeared that Lorenzo-Vera was annoyed with England's Dan Bradbury and Sam Hutsby, as well as Spaniard Borja Virto, who were playing in the group ahead in the 9.20am tee time.
Who knows, maybe the trio will blame the group in front during the second round of the BMW International Open in Germany?!
Lorenzo-Vera, it is probably not unreasonable to suggest, was already feeling a little bit annoyed as he was considerably over par when he let his furious fingers start tapping away.
He was 10-over par at the time and was heading for a missed cut and therefore wanted to get back to the clubhouse as soon as possible.
That wasn't possible, apparently, as he was allegedly kept waiting on every shot.
In fairness, that is an appalling pace of play. I would say criminal. And it truly is a bad advert for professional golf.
By day's end, Lorenzo-Vera posted a second round of 12-over 84 to reach 13-over after 36 holes.
His second round included as many as three double bogeys, six bogeys and a solitary birdie. The projected cut at Golfclub München Eichenried was 1-over.
We'll have to keep our eyes peeled to see if the alleged guilty parties respond to Lorenzo-Vera's accusations.
At the halfway point, it was Australian Daniel Hillier who led the way at 9-under after posting rounds of 68 and 67.
The defending champion is Haotong Li, also missed the cut with a similarly miserable experience as Lorenzo-Vera. Li posted rounds of 75 and 82.
