Sky need to sack the fucker. Keys and grey were hooded for a spot of sexist and idiotic banter. Spitting is far far worse. And in this case, he spat in the face of a 14 yr old girl.He made a mistake and not a nice one. He has apologised.
Sky need to reprimand him, subject to an investigation, fine him, give him a warning if appropriate and then let him continue in his job.
