Breakfast radio presenters. I really don’t want inane chatter shouted at me at 6.30am. I need something calm and sedate to get me up, so I refuse the radio in the mornings and listen to my own music.
I am much less tolerant with any radio station with adverts, so that just leaves me with the BBC stations.
And a few public transport annoyances - people sitting right next to each other almost shouting. Noisy or smelly food. Music played out loud, usually on rubbish mobile phone speakers which make even my favourite songs sound truly awful.
As you can tell, I find noisy people and noisy things a common annoyance. Unless it’s a Class 313 (and all the similar classes) - they can make as much noise as they like
