What something that’s completely normal in movies but would be weird and even psychotic in real life?

Trying not to answer the question in my own OP so I’ll have to describe. Something that happens in almost all or the majority of film or even TV and is totally normal in the film world that would not happen without some serious questions about comfort or believability in the real world
