So apparently, the engineers at the MTA have been trying to wrap their heads around an enormously pressing issue.
Yes folks, the issue we speak of is (cue drum-roll): Gum on the floors.
Apparently, concrete is much harder to clean than granite tile. However, concrete is much less expensive to install. According to WCBS, a concrete train station runs about $400k. Granite tile stations are well over $1 million.
So we are left with a major dilemma. Floors that are cheap, but a bitch to clean, or expensive and easy to clean.
Either way, the floors are dirty as shit.
