One should try to find out where architects planned guards, which were
later forgotten, by museum peoples. Hope it is clear. For example, here in
the city museum, its extremly easy to go in without paying those 10 DM,
they want for the "Zeitenwende" show. Just enter trough the basement. One
stair down, and you are in.
Maybe architects dont care.
In Berlin, I once left the toilet trough the wrong door, et voila....
Another thing is the psychology of guardspeople. I once entered, same
museum, a show from the backside. Seems that they concentrate on the space
between the place, where you should pay, and the entrance.
More examples ?
