Wedding planners - I sit near someone who has been planning the equivalent of a royal wedding during working hours for what seems like years now
People who take doctors and dentists appointments in the middle of the day so are out for most of the day
Dog and cat bores - no I don't want to see another clip of your pet doing something cute
People who are refused annual leave so ring in sick
People who talk to themselves about every single task they are doing
People who consistently call in sick on Mondays and Fridays but are never called out on it
