to give you a sense of time, I'll use my eating record to demonstrate what happened.

1st plate : I arrive and those fuckers immediately started squinting at me. I had no knowledge of the technique, so simply went about my business and dug into some egg rolls and beef and broccoli.
2nd plate : I'm started to feel a little swollen. While I'm slapping mounds of hunan chicken and fried rice on my plate, I notice them watching me. The waiter, the host, and even the fucking cook was peeking through the little hole in the door.
3rd plate : I'm hurting now. I decide to ignore the pain (not realizing where the attack was coming from). 3 spring rolls and a weird hot cabbage dish later, I'm sweating and my wife comments that I don't look good.
4th plate : It's time to go home. It was all I could do to finish my meal and they're still lingering around, watching me as if waiting to see what I'll do next.

I barely got out of there, but it was too late. I went home and exploded.
