On the Down Low

I take the train work. At the stop just before my station, there is a message that flashes by. It's an automated screen with a blue background and dark text.

We go by much too fast for me to read it; the only way it would be visible was if the train were not in motion. Since, it's between stops, I am pretty sure it's supposed to be subliminal advertising.

Since I discovered the existence of the ad, I make sure to keep my nose buried in a book so that I miss the message.
