I gather there has been a programme recently on the television (I didn't see it) which involved a number of semi-famous people being locked up together in a house for several days.
The programme was produced by Channel 4, which prides itself on being "challenging" and "controversial". This apparently means, among other things, celebrating the British mediocratic ethos.
It seems that one of the so-called "celebrities" was rude to one of the others, in a way which fell foul of currently fashionable rules of etiquette.
Honestly, what do you expect?
