About two years after my company was bought by a larger one, I was the first person at the office one morning, only to find someone waiting outside the doors. Before I could ask, he introduced himself as an employee from an out-of-town office, and produced a company ID, so I let him in with me.

We had been told to expect some visitors from that office, but I was almost hoping he was not legit, since most of us at my location still do not have a company ID, so I couldn't really say if his was real or not.
