This is gonna sound silly but I don't know where else to turn. A few days ago I bought some oatmeal at McDonald's (I think they use Quaker oatmeal) and I bit on something really hard, I couldn't chew it so I took it out of my mouth and I swear I saw a piece of human nail. I'd been working for 16 hours and awake for almost 24, so I was very sleepy, I looked at it for like 10 seconds and threw it away, didn't give it much thought at the time.. a few hours later I started thinking, could it have been a human nail or does oatmeal sometimes has hard pieces, like uncooked or overcooked bits.. I of course have eaten oatmeal before but I can't seem to remember ever finding something like that, although maybe I just threw it away and didn't think about it. This is driving me crazy lol, any opinions, experiences? Thanks.
