Not happy i stopped to let people cross LY16FGU

At the start he came fast around the corner and was going fast till he had to stop because i was letting children cross the road. It seems he was not happy and from then till i turned Right he kept tailgating and when i indicated Right he blew his horn within a few seconds of me stopping because he could not get pasted me. You can see him shouting and waving his fist as i was turning.
