spivonious and tsl give the best advice.

Don't be preachy or demanding. Pose it as a question that you're sure they'll want to solve. See if you can frame it as something that won't cost them much or anything. Maybe there's grant money for this sort of thing. Or maybe if you went one level up, the person might say, duh, what a no-brainer, let's put in a modern rack in the right location.

But don't listen to me as much as to tsl. Follow his advice.
