My name is X and another person also named X tells me to gather their documents from the office. Other X also signs a paper for me that says I'm allowed to do this.

I ask the office clerk: "Hi, I'm here to retreive the documents for X". He checks my ID and gives me the documents without asking for written permission from the other X.

It's deception by omission, but there is no fraud. I was legally allowed to do this. It's also a win for everyone because it avoids complications.
