Ive had a fair share of UPS drivers coming to my house, but what about USPS drivers? I believe I've had a few USPS investigations, Im not 100% sure, but none of them had a driver come to my house to check up on any packages. A refunder just told me that USPS drivers often have drivers knock on doors to follow up on investigations. Is this true? Do they usually come to peoples door to talk about missing packs, and am I just lucky to not have had a driver come to my house yet?
