Tonight John brought me home a Burger King salad. I started eating it and noticed that one of the types of lettuce had darker spots on it. Almost every piece of that type of lettuce had it. I know absolutely nothing about lettuce, so I'm worrying if it's ok. I stuck it in the fridge until I can find an answer. The lettuce isn't wilted and the color isn't brown, it's like darker spots on top of the green. Any ideas? If it's okay, I'll finish eating it but I'm kind of afraid to. And if it's something bad, do you think the few bites that I already ate are going to hurt me?
