My office is open plan and my colleagues are wonderful BUT there's this one person who eats nuts with the crispy edge. I don't know what they're called but they're so noisy to eat and to add, he's not the quietest eater at the best of times so the horrid crunch sound and then the wet eating sloppy sound drives me insane. It's at regular intervals of the day too! I take myself off for a long poo at these times when it gets too much!
