Am I the only one who pictures a dystopian sci-fi movie when the words "oxygen bar" are uttered? I'm seeing a crowded bar full of a menagerie of aliens. Dark, lit with neon from below the plexiglass floor panels. Various species of aliens are inhaling oxygen from cones attached to the ends of long flexible tubes. The bouncer (who has eight arms) has to throw out a customer who got belligerent because they don't serve Methane. Our protagonists enter the bar just as the bouncer is brushing the dust from his hands and turning to go back inside.

Nah, it's probably just me.
