Okay so you know those cool multi alien species bars in Star Wars and other science fiction media, well I'm working on one of those for my story and wanted to know about some potential issues with the whole multi alien species mall (recreational area).
So this mall has four parts to it, the parking slots, the public area, the housing districts, and maintenance area. The parking slots and housing districts speak for themselves and are ship model and species specific. The public area is for shops and other set ups like that of a mall and the maintenance area is just the boring stuff like power production, cleanup, monitoring, etc.
Their are only 98 sentient alien kinds in the universe so far and all are carbon based with different biochemistries, they all breathe oxygen with an exception of two. Body shapes are diverse so not every species is humanoid either. The majority have bilateral symmetry with four limbs.
This giant mall is a huge space station, that orbits a gas giant. It has its own artificial gravity and other systems to protect the inhabitants from the harsh void of space.
And so my question for all of this is what are some problems that will arise from this set up?
