Presumably he’s talking about shouting abuse at people who work in 999 call centres rather than doing technical support for fucking useless Sony Vaios[1]? Still not as bad as throwing stones at fire engines, but rather closer to the "deserving the birch" end of the spectrum than the "clearly understandable".
[1]The Sony Vaio is a fine computer but its technical support people are in my experience a god damned disgrace.
