In my dream world we would normalize things like eating on a zoom call. People gotta eat, it’s no big deal. Maybe if they’re audibly slurping soup that’s a problem in terms of noise, but that would also be a problem during a boardroom meeting.
(I once got in a lot of trouble for having a bowl of cereal while I was a silent participant in a call with a client at a fintech company, so I understand that attitudes like yours are common.)
