Top spot goes to hayfever cos it's so useless and snotty.
Second spot goes to sweaty people who don't wash and/ or dopn't wear deodorant. THIS IS THE FUCKING 21ST CENTURY AND DEO AIN'T EXPENSIVE.
And third spot goes to...drum roll pls...tourist who stand in your way especially when it's a) raining, b) you have no umbrella and c) a car is driving straight for you.
