Only met one in there Christmas Eve 2011,St Mirren V Rangers,I started to hear a dissenting voice behind me,so did my big mate who had him by the throat in an instant,he squeeled like a pig,now I am nearer 80 than 70,when the pig said you are going to jail for that,its on film,I carry an oxygen cylinder with me,so I showed it to him and said if he goes to jail you are giong to the Royal. At that point Mrs Mm appeared and ejected him,peace reigned. PS the CCTV footage vanished
