Cash ATM Security

No, this is not a technical/crypto post. I was getting lunch today, somewhere which has one of those non-bank ATM cash machine. This guy came in, dressed very casually in t-shirts and shorts, and exchanged a metal box from the machine. I had to think that he just refilled the machine with new cash. I was surprised by his casual dress code, and I watched him exit the deli. He walked a little down the street, got into his double parked pickup truck and drove off.

Question to ask — how many little metal cash boxes does he have in his truck? Leaving it double parked on a city street — is that a good idea? Do you want his license plate and truck description?
