As I, too, ride public transportation in SoCal, let me say that your post is spot on.
As one who rides Metro North to NYC every day, I can also vouch that there is a certain class of rider who are always the loudest, most obnoxious people. They hog up an extra seat with all their crap. They also tend to slow down the conductor because they act surprised when asked for a ticket and go through a whole pantomime of trying to find their “lost” ticket. Eventually the conductor shrugs and moves on so they end up getting a free ride. They know that they will never get challenged for their behavior because...racism!
Thanks. A fellow traveller dares speak that which must not be said. 👍
