The one time I actually went as assistant to Science to actually assist and be helpful, i got constantly stopped by security or questioned what i was doing even though i had RD's permission.
Its fun sometimes to be the guy who goes around the department helping people out with the simplest of tasks, but a lot of people also think their workplace is holy and really do not want outsiders to mess with it.
And about bridge hobos, i just see it the same as people gathering on a town square to hang about, see the life move around and what not. Its not maybe the greatest place to hang about, but it is also the most central place of the station community and that's kinda what attracts people.
