There's quite a few rules in golf, but one of the biggest rules spectators must follow is turning their phones on silent while following their favorite golfers at a tournament.
One fan forgot to do that at the BMW International Open.
The European Tour event features some notable international players including Lee Westwood, who had to stop mid-swing during the second round of the tournament after hearing a patron's ringer.
While he seemed visibly upset on the course, Westwood said "that's all right, just turn it off," and continued his round.
After he completed play at Golfclub München Eichenried in Moosinning, Germany, he gave a quick tutorial in case anyone was confused on course etiquette.
"Much like golf, people overcomplicate things, but it really is this simple," Westwood says before silencing his own phone.
Putting your phone on silent.

Westwood, a 24-time European Tour winner, is in good position heading into the weekend. He is currently tied for fifth place (7 under) and just four strokes back of the solo leader Martin Kaymer.
Westwood last won at the Nedbank Golf Challenge in November and is currently ranked as the eighth winningest golfer across the pond.
