When I was in college, I was a waitress at a restaurant which was quite popular and well-known for their family style, all-you-can eat turkey dinner. People would wait in line for hours on the weekend to eat there. It was the most disgusting place ever. They recycled all the uneaten food. Any turkey left on the serving platter got dumped back in a bucket in the kitchen. (I don't remember if we were told what it got used for, but I'm pretty sure it went into the soup, which is totally gross). But I saw wait staff go get "bucket meat" out of that bucket, nuke it, and bring it to customers who asked for seconds instead of waiting for in line the chef to carve fresh meat. When people first sat down, we would bring bowls of cole slaw, cranberry sauce, bean salad, butter; trays of celery, carrots and olives; and rolls to the table. We were supposed to dump whatever was left in those bowls back into the tubs in the kitchen to be scooped out and served again. I refused to do it. I have never seen anything so foul. And to think people lined up around the block to eat someone else's table scraps.
Amazingly, I still eat out. I just try not to think about what goes on and I never send food back!
PS -- No, the restaurant is not open anymore
