What was your worst restaurant experience?

Carmen and I spent a couple nights on Pender Island at a fancy resort. The first night we decided to get dinner at the restaurant, which was $$$$$ but thought we would do something special. (Keep in mind, the only other place to eat on this island was a pub which closed the kitchen early). We waited just to get seated close to 20 minutes. We finally were seated, and waited another 20 minutes just for the waiter to come order our drinks. He took our orders, and we ordered our food at the same time, then never brought us our drinks or food. Finally a waitress saw us, so she re took our orders. Then we noticed another couple waiting to be seated. They were finally seated, and we had just gotten our drinks. 15 minutes later they were eating, BEFORE US, and it looked like they were eating what we ordered. I called the waiter over, and freaked out. He hardly apologized, and tried to give some excuse about why they had their food. After 1.5 - 2 hours, we finally had our food. They gave us a complimentary drink to make up for the wait, but didn't offer the meals for free or anything. And they weren't even busy, there was only 4 or 5 other occupied tables.

Carmen and I went to a restaurant in Nicaragua, which was supposed to be good according to Lonely Planet, but obviously had fallen apart. We ordered coffee to start, and when the guy brought the coffee out, the mugs were dark inside. Turned out they had 1/8" of dust in them, and he poured the coffee into them. Carmen's had cobwebs all over the top. Our scrambled eggs were runny and uncooked inside. Our hashbrowns had heart attack written all over them.. soooo greasy inside. The toast was the only thing we could keep down, but the jam was moldy and the butter was full of dead flies. The restaurant itself was totally rundown, and the kitchen looked like a back alley. The worst part was, the guy wasn't from Nicaragua. He was actually from Victoria BC, about 2 hours from where we live! Story was him and his wife ran this place as a hostel/restaurant, but she left him, and it fell apart.
