Bill Clinton goes to McDonalds, worker didn't know it was him

Gotta be a really funny time when Bill Clinton walks into McDonalds and the workers don't even know it's him. I guess these ladies don't care about Bill Clinton in general. Once they found out who he is, they seemed excited. But it's Bill Clinton? How does someone not recognize him? Bill Clinton has a very distinct look and appearance. There's not many people who look like Bill Clinton, ya know what i mean.
