United States Postal Service at 2215 Artesia Boulevard, Redondo Beach, California.

This PO doesn't provide a safe means of posting mail outside of their operating hours of 9 - 5 on weekdays. They're aware that the boxes in front of the PO and in the neighborhood are unsafe due to pilfering, but have no plans to add a safe mail slot from the outside of the building for after-hours drop-offs. The inside slot is not accessible when they're closed unless you have a PO box here and a code or key for the door. This is not customer service.
