Pro tip: once people are working in offices again, if this happens, whip out your phone and dial the room directly. People tend to speed up when they realize they are blocking someone far away from dialing in, even when they don't seem to give a crap about the people standing just outside the door.

Of course, the ones who see your name dialing in and then spot you outside the room a few seconds later will be confused at first, and later may get annoyed with you, but remember, they were the ones who were being abusive.
