Remember to be kind
With the current state of the world, everyone is on edge and quick to anger. Approach situations from a perspective of kindness. You never know what someone else is going through at the time, and responding with a default of anger to what seems like a personal slight is only going to make things worse.
Lots of people around you are struggling with mental health, anxiety, loss, grief, and more. If someone does something thoughtless, it’s best to just let it go. If it’s egregious enough to require correction, start out by asking them if they understand what they were supposed to do (in a kind way) rather than assuming that they were purposefully being malicious. They almost certainly weren’t doing it on purpose, and even if they were, is it really worth getting into a fight over it?
It’s also worth remembering that other people aren’t necessarily in a space for the same reason as you, and they might be inexperienced with the use of that space. Something that seems obvious and straightforward to you might be a confusing mess to other people.
And the inverse also applies; if you’re the one who has caused other people to blow up at you, regardless of intention, you don’t know what they’ve been going through either, or how many microaggressions may have led to them boiling over.
tl;dr: Assume good faith in others.
