Those who speak loudly in public places. We went to an exhibition yesterday (cramming in an uncharacteristically cultural undertaking), and went for a bite to eat and a couple of pints in a nearby pub afterwards. The bloke in question was not only loud, but arrogant, stupid, peppered his conversation with the F word (one word in four or five, I'd have guessed), but was also loudly and unashamedly racist. I thought that even those who held such views would voice them with a degree of circumspection these days, but it appears not.
