worst thing i ever found in my food was what i thought was a piece of semi-melted plastic in the bread of a sandwich. took it to the attention of the manager and had my meal comped. went in again the next day and the manager came over and said that she had investigated it, and it was actually just a really hard sun-dried tomato that was supposed to be baked in the bread. she just wanted to make sure we knew that it wasn't actually plastic. she even let us examine it to make sure.

worst thing i ever saw in someone else's food was from a friend's bagged salad at a grocery store in Rome. she got halfway finished with her bowl of salad, then saw half....HALF... of a small frog in it. so very very gross.
