People with a BMI of 30 and up should NOT board the bus when I'm on it.
Well, they can, but they are NOT allowed to try and squeeze themselves in the seat next to me, protrude to an unnatural or incongruous extent and then accordingly squash me between them and the window.
I was reading a book and couldn't even move my arms to turn over the page! Seriously. How can you be that fat and not have the slightest inkling of what kind of uncomfortableness you cause others by literally shifting your weight around.
To top it off the fat woman even gave me a 'Move a little will ya'-stare.
Really. One ass per seat please.
