It turns out that the male nurse was making fun of the Armenians accents in Koscheks's team (racist prick!!!), and not only that, but Kos also calms his team down after the inccident, and even tells his team to ignore him from now on, and even goes back to the male nurse and apologizes for trying to assult him.
Heres the link with video:
Kos was right when he said that GSp just hired him to push his buttons, call me crazy
but I think that's mighty cowardly by GSp.
