If one is in a public or shared restroom at a urinal or in a stall and the person at the adjacent urinal or in the adjacent stall sneezes, is it appropriate to say "bless you" or "gesundheit" or another culturally appropriate post-sneeze statement? Is it appropriate to say nothing at all?
It's cold season at the lab and the fact that I do not know the answers to these questions is becoming a source of stress.
