Any floor on any train is nasty. You don’t want anything to touch it including your feet. As I shimmy my slight 6’2″, size 13 shoe into a space, dude across from me has his bag ON THE FLOOR between his feet where my feet would go instead of on the seat creating the aforementioned Man Rule barrier asks me “if I got it?” Meaning didn’t I amputate both of my feel to accommodate his ridiculous, unsanitary mode of travel. Magically he put the bag on the seat next to him after I “didn’t get it”. Knucklehead.
