Attacked by a security guard at standard bank greenstone

Apologies for some of the language however this is the actual story as it went I was trying to get to the enquiries counter with mom and she's in a wheelchair so disabled people are allowed to go to the front of the que... The security guard questions me where are you going... It's none of his business 1st off... Next he says the woman from the counter is not there so I need to wait so I said no problem I'll wait at the counter for her... He's like no you can wait outside... So I said I can't stand too long as I have Neuropathy... Dumb **** has no idea what I'm saying so Daniel take the wheel chair to push Nana in next thing he's telling us to **** off... So Daniel told him to **** off as well... I was behind them next the security guard grabbed me and pushed me so Daniel grabbed him and shoved the little ***** into the doors... He tried grabbed Daniel by the neck and snapped his chains then of course all the other previously disadvantaged assholes started chirping and swearing typical of that nationality... Then there were the heroes from night guard of course and cops were there but they didn't give a ****.. So nightguard dude escorted Daniel out but told him to report the ***** to the Centre management... So I had to leave my mom in the bank and go there to lay a complaint.... I called Chris to come there to help me fetch my mom in case they started **** again.... But as I left to go to Daniel I took my jersey off then they saw the tattoos suddenly they all shut up... There was one of the spectators that wanted to beat up Daniel he wasn't even involved but the cop held onto him
