>>5445438It wouldn't be anywhere near a proper upscale 40k/sci fi noble restaurant if every booth was not the size of a feudal feast table, able to accommodate everything from the noble who intentionally keeps himself fat as a status symbol carried around upon his hover chair, to high ranking Archmagos or allied Fabricator General who has become one with his Abeyant. The best Lucian restaurant, held to the standards of ancient Terra and wealthy Manachea, would surely have its VIP booth specifically a throne set for TalOS size and grandeur.
Also pretty much on every Primarch touched planet, they made Primarch sized chairs for such occasions. In unremembered empire it was noted how Roboute specifically designed a particular room where the small chairs of mortals would be up front, the bigger chairs of space marines in the middle, and his gigantic chair far off in the back, but in such a way via visual illusion that everyone's chair seemed to be the same size, a bit like the "Round Table" type deal.
Ferrus Manus had his big throne in the feast hall on Fenris too. At some point as we get larger and larger, our booth may become less a Throne and more a space to park our dreadnought sized form. Just like the post indomitus Fabricator General when they attend the Terran Council, their full form is the size of a building and carried via mass lifter, and there's a huge tunnel for it just outside the council chambers, and a space for the tank that contains his organic body to stick through Dune Navigator style.
