Shop staff who tell me they don't have any size 12s/38Bs/39s left because 'it is a popular size'. STOCK MORE, THEN!!!
News programme presenters who say 'Alex, thank you' or 'Lindsay, thank you' instead of 'thank you, Alex' or 'thank you, Lindsay'. Even the roving reporters do it - 'Jon, as you can see...........', Krish, bombs have been raining down here all day...........' Why do they do that? I can't think of a single good reason. Channel 4 News has a lot to answer for.
And don't get me started on apostrophes.
