I was just having my morning deuce at work, and there are only two cubicles. Some douche comes charging into the one next to me. Seriously, wtf. There are three floors and six cubicles to choose from at 8:50 on a Monday morning. Toilet etiquette much?
It's not like there was any hesitation either, he could see the one next to it was occupied as soon as he walked in, just the sound of restroom door opening and stampede for the cubicle in one uninterrupted motion.
