Foster was smiling, laughing and joking a few hours after this footage was filmed as his player Matthew Fitzpatrick claimed his second PGA Tour win at Hilton Head with a simply ridiculous shot in extra holes over fan favourite and defending champion Jordan Spieth.
This clip came on No. 16 and at the time Cantlay was only two strokes adrift of then-leader Spieth who had reached 17-under.
He clearly needed - at the very least - two birdies or hope that Spieth or Fitzpatrick would make a mistake or two.
Foster? He was having absolutely none of it. Last year one tour pro joked that Cantlay would be 'the next villain' on the PGA Tour after LIV Golf snapped up all of the controversial figures such as Bryson DeChambeau and Phil Mickelson.
If that is true, then Cantlay is certainly fully embracing his new role as the PGA Tour's bad boy.
I mean, just look at Foster's reaction here:

Foster previously spoke about 'pathetic' pace of play when we caught up with him before Fitzpatrick played The Masters.
Asked about pace of play, Foster said:
Cantlay's pace of play has irked others. Sky Sports commentator Andrew Coltart went after Cantlay during the final round coverage from Hilton Head.
Brooks Koepka was the first to lash out at the brutally slow Cantlay during the 87th Masters.
Cantlay chose to point the finger at everyone but himself. Then he brilliantly trolled himself after making a hole-in-one.
