Shocking footage from the US Open has left viewers furious worldwide.

After a thrilling five-set victory, Polish player Kamil Majchrzak tried to gift his match-worn cap to a young boy. But instead, a man standing nearby grabbed it and stuffed it into his bag. The stunned child could be heard asking, “What are you doing?”

The clip went viral, with fans calling the man “selfish,” “a coward,” and “a bully.” One commenter wrote: “Imagine being grown and stealing from a kid. A new low.” The man has since been named online as a millionaire CEO, sparking even more backlash.

Majchrzak quickly stepped in, posting on Instagram: “Thanks to @asicstennis I’ve got enough caps. Help me find the boy.” Hours later, he happily confirmed the child was located, adding: “I am impressed by the power of the internet. We got it! All good now.”

The incident shows how a single act can spark outrage but also inspire kindness. What do you think — should fans who ruin moments for children face consequences?
