Why do I consider the rank and foul odor of someone taking a shit wafting into a commercial kitchen and onto clean cooking surfaces and food gross???
Really?
You must live in one of those homes you seem really defensive about this bathroom/kitchen layout lol
Yes, that is my question, the odor consists of just gas molecules, as you correctly said, even viruses are 1000x times bigger than molecules. Do you imagine that they are special gas molecules that contain a shit-atom because they have been produced by shit-bacteria? It's just smelly gas. Unpleasant? Maybe. A food hazard? No.
I'm just trying to challenge your strange misconceptions about poop smell. I'll wave my hamburger through fartclouds no problem. You must run for the hills any time anyone farts, as you seem to believe your nostrils will get dirty.
