If a girl is beautiful and has already boyfriend/relationship then she doesn't want to hang out with other people and wait till clock hits 5 PM. Same can be said about married people but at least they will hang out sometimes. Single people especially guys want to hangout but as soon as all girls are gone, it becomes useless to stay. Personally I prefer we just stay stickily professional. But people do otherwise more often than not
