OK, I got one. There is a proper etiquette for public transportation, be it train or bus. You let the people get off before getting on. It is courtesey, it is a kindness, and it's not that fucking hard. I know you're in a hurry to get to work cause little Tommy shit himself on the way to pre-school, but bowling my ass over to get on the fucking train isn't gonna magically make the train go into hyperdrive. YOU AREN"T THAT FUCKING IMPORTANT, OK?
