Yeah gods, who really cares, the controller made an error, the BA pilot was slow to push, the stobart pushed before he was meant to, as he got sick of waiting for the BA. The controller tried unsuccessfully to rectify the error, the BA pilot got stroppy.
Basically this sort of thing happens at busy airports, most ATCO's just live with it and don't feel the need to post on u tube, pprune, facebook or whatever. Enough.
