That’s due to a panic response and people pressing against the doors so you can’t pull them open. That only happens after a certain amount of people. The couple dozen max in a bathroom or most office and conference rooms won’t have that issue. But all the doors from the hallways out will swing towards the path of egress though.
Codes stipulate the occupancy amount that requires it, I believe the model building codes of NA and most of Europe calls for 100 people occupancy. Unless it’s been changed in the last few years.
