What would be some of the issues with drinking your coffee on the toilet while you’re taking a dump, if your coffee cup has a lid? - lemm.ee

My coworker was trying to get me to do this with him, he said at the previous company he worked with him and two others would each drink their coffee in their stalls while they talked. So I see that as a big issue if you don’t like to talk while you smell poop and drink coffee
I wonder what they talked about while shitting ?
