So true! I was at a one-day event last week, and presentations were over-running as usual, mainly cos some gobshite who liked the sound of his own voice a bit too much was "asking questions" of every speaker. In reality he was making speeches of his own that had no relevance: and we missed our coffee break cos of it
I also hate people who don't say thank you when you hold a door or step out of their way; and people who take two seats on a train whilst other people are standing; and people who slurp on their food in public - yeurch
