For me, it's the slurping and the rustling and the crunching. And cutlery tapping against plates and teeth. And the wet sound of someone moving food around inside their mouth with their tongue; cheeks and lips flexing and slurping against each other because they took too large a mouthful, barely even looking at their food because they're staring at something else. And the snorts of breath around it as they need to keep breathing around a mouthful of food. And the sound of teeth clicking together as they munch too hard. Greasy fingers wiping on themselves or their desks if they even bother to wipe them before tapping away again at a keyboard. Back of a hand scraping across their face to remove detritus.
