I thought this would be an interesting, fun topic.
What was your worst restaurant experience?

Mine? Well sometime back in the late 80's I was on a date with my girlfriend at a Chinese retaurant. One of the things we ordered was chicken friend rice. Well, there were LOTS of dead roaches in the dish that were kinda hidden by the brown color and texture of the fried rice. My girlfriend and I ate some I am sure, we were about 1/4 of the way through the dish before we noticed. I thought I was gonna puke, but didn't.
I made sure I spoke loudly when I pointed this out to the waiter. He actually asked if I wanted another portion.....
