I get annoyed when someone is hacking up a lung 3 feet from my food. If I disappear for a few days, I probably came down with pneumonia and am cursing the day I was seated next to Typhoid Mary.

I considered saying something before I leave, but I come here all the time and don't want to make a scene. Plus that's not my style. I'd move or request a new table but this place is packed today, probably because of the snow.

What do you do when someone is hacking up a lung a few feet from the food you're eating?
