People saying REEsearch instead of reSEARCH. Drives me mad.
People who dither in car parks, esp. multi storey ones, blocking the way while they wait for someone to,leave - when any idiot can see plenty of spaces on the next level. Same person will then take 14 manoeuvres to back the car into a space they could easily have driven into front first.
People who sit by the window on crowded buses, plonk their bag on the other seat, and then pretend to be so engrossed in their effing phones to notice several people standing, who are too polite/reticent to ask them to move their bag. (I do not fall into the 'too polite/reticent' category.)
About a million other things, but I'm off to bed now, with a cup,of tea and a book.
