Anyone ever have a public outburst?

After watching one too many videos of people losing their cool, I have to ask, has anyone ever found themselves in public with wanting to uncontrollably rage?

When I was back in school, I preferred doing my assignments away from the house - less things to distract me in a public place. I was going through a particularly stressful load with school, work, and personal life at that point.

I went to a nearby Taco Bell to pick up lunch, then I settled in to take advantage of the free wifi for a couple hours. Laptop in front of me, mouse on my right, detachable keyboard on my left, book in the middle. Headphones helped drown out the noise of the place, but when one set of ladies sat next to me, the music couldn't drown out their loudness, and boy was one in particular pretty animated. (Not sitting directly next to me, but other side of the table from that one)

So I'm getting a little distracted and annoyed by her loud talking, unaware of her surroundings. I guess the conversation steered into a moment where she felt the need to start beating her surroundings with the palm of her hand to emphasize just how funny her story was. Problem was, one of her palm strikes hit my detached keyboard and struck all manners of gibberish onto my screen. Whatever in life was bothering me, that was the last straw.

I tore my headphones off, looked directly at her and yelled for the whole Taco Bell to hear, "DON'T YOU DARE EVER TOUCH MY s-$-$ AGAIN!"

"My bad..my bad...my bad.."

"NEVER! EVER! UNDERSTAND?"

We got into a brief staring contest, unconsciously finding ourselves both on our feet. My fury must've been blaring through, because she quickly turned away. I was waiting for her to say anything stupid, but, she didn't. Her and her friend gathered up the remains of their meal and left. After a few minutes of the entire Taco Bell just staring me down, concentration hopeless, I left, too.

Luckily, no public freakout fights under my belt. But how about y'all? Ever lost it anywhere in public?
