I'm not sure if I'm just too easily irritated, but I've been wondering about how to deal with this for a while. At work, there's someone who sits in an adjacent cubicle who likes to crunch ice fairly often, and someone in another adjacent cubicle who likes to pop gum sometimes. Those are the kinds of noises that I find difficult to tune out, and it can be distracting (and I find food-related noises particularly irritating due to a mild disgust factor). I'm wondering what the best way would be to deal with that? Should I calmly confront them about it, or should I write an anonymous note for them, or should I try to tune it out and ignore it? I'm somewhat surprised nobody else has apparently mentioned it.
