Dear God. Sitting having breakfast in an economy type hotel chain, on my own for work, and the man two tables down is eating so noisily that I can hear every chew, even above the chatter and general noise. His table mate is perfectly fine but Noisy Eater (NE) has smacked his chops and talked with his mouth full throughout. NE has a whole extra noisy level to the norm.
I know IABU, and sensitivity to this is a thing, but I have the rage. My problem, I know, and I guess he's harmless (but I'm not right now).
