Maybe a couple of fighters have stinky feet and rather than singling them out and embarrassing them they just instituted it for everyone.
Any Europeans in this thread? Is it still a big deal that an Adult male shouldn't wear shorts if he is old enough for pants or is that tradition a bit antiquated. If it's still in effect, expanding into the Euro market might be valid reason for requiring pants.
Actually upon reflection, and looking for other media reports... as far as I know Benson is the only one that has been told this, it's not a policy that was implemented for all fighters (and maybe not even a policy, just a suggestion).
Everybody good, plenty of slaves for my robot colony?
