The MTA's etiquette campaign is underway. The color coding is clear. Good people are green, like the nice man offering his seat to the pregnant lady. (The gray guy with a tie looks a bit embarrassed, don't you think?)
Bad people are red, like the dude spreading his legs. (Again, the gray guy with the tie serves as witness.) And MTA employs are blue. But how do you depict someone who's not feeling well?
Without making other passengers feel the same way? So just remember:
Don't be red.
Most of us are gray.
Hope you never feel greenish.
