Some people might not really understand how they are supposed to act in public places. Maybe they weren't taught the right way to behave outside their home, or they just don't realize that their actions could bother other people. So, they might do things that seem rude or inappropriate, but they don't actually mean to upset anyone.

What's okay in one place might not be okay in another because different cultures have different rules about what's acceptable. So, when people from various backgrounds gather in one public space, what one person thinks is fine, another might find offensive. This can lead to actions that seem disrespectful, even if no disrespect is intended.

Some people just care more about being comfortable or doing what they want than following social rules. They might think that since it's a public place, they can do whatever they like, whether it's loud talking or spreading out their things. They believe their personal freedom is more important than keeping to social etiquette.

Sometimes, when people don't follow the usual rules in public, they're actually trying to make a point. They might be upset about certain rules or societal norms, and they show it by acting out. It's their way of protesting what they think is unfair or too restrictive.
