This is outrageous. I own my business. I have several calls daily. Not a single person I work with or for would bat an eyelid if I had to pause a call for 15 seconds after I had locked out my family.
There are a couple of specific exceptions. I occasionally have to go on TV or radio as a spokesperson for my biz. In that case I might wait till the interview was over, but that is likely to be a ten minute wait tops.
Also in those cases I always make OH aware of the timings as I ideally want to minimise background noise for that short period, he then sometimes chooses to go for a walk or up to read or whatever.
I also chair virtual, live conferences which can be up to an hour long between breaks and I make him aware of those timings too. I'm being broadcast live on camera so ideally I would want to stay at my desk, but I could shoot off a quick text explaining and letting him know when I'd be free.
If it was an emergency - I might be able to cut my camera and dash off, that said they are often repackaged as videos for clients so not ideal.
However I would for SURE make sure that I hadn't locked out my partner and kids before the started conference started.
I sometimes see him hovering outside the front door by CHOICE because he doesn't want to disturb me, but I wouldn't actually mind if he chose to come in, and I certainly wouldn't bloody trap him out there in the first place. And definitely definitely not several times.
He's disgusting. You get my first ever LTB. What a prick.
