You're on a public bus. Remember that the next time you think it's appropriate to insinuate a class divide by reserving a seat for your fake Louis Vuitton bag. It's hard to convince the world that you deserve special accommodations when you can't afford cab fare.
Taking mass transit is mortifying enough. Don't degrade us further by requiring your permission to plop down on a piss-soaked seat. Just put your Prada knockoff on your lap. Please and thank you.
