This is the moment a man punches a bystander in the face after finding him staring at his girlfriend’s bottom.CCTV footage filmed in a shop in Lincolnton, North Carolina, shows a couple at the counter talking with the clerk when the boyfriend notices another man is gawping at his partner.He approaches him aggressively and delivers a left hook to the man.The lady is visibly embarrassed and asks her partner to apologise but he follows the man out of the building.This behaviour did not reportedly shock the staff of SEA Wireless, who decided to get a CCTV camera after a spate of break-ins and daylight robberies.The footage was filmed on August 8.
