Tournament etiquette

I let my ball 3 drain out in a tournament because a couple of people behind me said, “he’s got it, it’s over. He can drain out now and it’s done” and my opponent echoed it to me, saying, “that’s that, you got me.” So I let it go and fell about 5,000 short after the bonus piled up. I wear earphones whenever I compete now. Everybody was apologetic, but I was out. I wasn’t too mad, because I know I should have put myself in the clear before the bonus, but sometimes you are just ready to let it go and move to the next round.
