I was just jumping torandom tvtropes pages, when I came across this one:

Comparing to EP, I think you can see many similarities (and there is a mention of how they were used in Planetes) - much of humanity lives in crowded environments with little privacy, yet most people do not want their trysts to be public. So it would make sense that something like this is pretty widespread out of necessity.
That thought led to another: this is a kind of environment with obvious adventure potential (secret meeting place or hiding place, room for character development, setting for some event, way of evading pursuit, place to infiltrate, etc.) yet it is not a standard location to most people (in the West, at least). What are your examples of similar locations in EP that might be great for description, action or just exotic-yet-logical flavour? What is going on in the hydroponics bay, or robot storage compartment? When the eccentric contact wants to meet you, where does he set up the meeting?
