I totally see your point, which is why I mentioned this really depends on context. I’ve worked in places where people actually did stretches or meditation during their breaks and nobody cared for it. But I can totally see how that wouldn’t fly in other places.
Also, from experience - some people will still talk to you even if you have headphones and your attention on the phone.
In theory it would, in practice good luck holding it in if it’s really diarrhea.
