What a weird take. If I'm also in the bathroom, I can tune out all the other noises around me because everyone's in there to do the same thing. If I were on the phone with someone, paying close attention to what they're saying, and then I'm treated to a thunderstorm of bowl challenges, I'm going to be annoyed.

Humans pee, fart, and burp. That's perfectly normal. And yet, it's considered basic politeness not to do those things in a freaking business meeting if you can help it.

At the end of the day it's very easy and free to not shit while on a conference call. I think 99% of people would prefer a shit-free conference call, so, maybe we're all spoiled.
