Finding two finger nails in my lemonade at Chick fil a?

Yesterday I went to Chick fil A and I found two finger nails in my lemonade or what I believe to be that. I even had someone else look at it, and they agreed that it looked like that. 
Will this affect my baby? I didn't swallow it or anything, I spit it out and threw away the drink. I honestly don't know how it could have gotten inside my drink. I would have said something but I ordered to go. 
Just a little worried and grossed out.
Thanks!
