What I find curious is that a rider who got on later blamed the MTA for their shitty service. As much as I have had my issues with the MTA, I can't blame them for this shitshow. You never know when someone is just going to pop a squat and drop a duece on the train. The dude did so after the train left the Brooklyn Bridge station.
I really feel sorry for the person who has to clean that shit up. My sympathies to you whomever you may be. That is definitely NOT in the job description.
Here's a little travel music for your commutes. Enjoy ;)
