PSA is a public service announcement, an awareness campaign.
It could be as simple as teaching everyone to walk on the same side of the footpath in each direction, to demonstrating how quickly a fire spreads and ways to prevent and react.

When entering a closed space other people are exiting (elevator, bus, train, etc) you can just… wait till they’re out. It’s that easy, nobody’s actually forcing you to cram the inside full to double capacity for a bit!
This is apparently new information to a significant amount of people around me
Not only that, usually lettinf people out fully and then going is is faster than getting all crammed and sruck trying to enter.
