Alcohol affects people in different ways. Some people get silly when drunk, some people like to get naked, and some people like to bite security guards in the leg!!
This dude says he was standing up for his buddy who was being ‘picked on’, on the bus. But the confrontation with the driver led to the security guards showing up. Not long after that the drunk guy was wrestling on the ground with the security guard and that's when he was bit in the leg.
He admitted to the police that he he’d drunk 20 pints of Stella because he’d had some bad family news, and that was why he was drinking.
