I am trying to understand the contention that all is fine as it was your postal worker who signed the form.

That it was signed for by someone other than Ed or a member of his household is a problem. It may be Covid. Apparently nobody, including me, has in these several days called the post office to see if the rules have changed. If I were to go to mail an item, signature required and as I handed it to the postal clerk she signed the form saying the item had been delivered because, after all, it was in the hands of the USPS and that was sufficient proof of delivery to the recipient, no one would say that is ok.

USPS's website is very clear that the recipient is to sign the form. It does get a bit tricky as of course here, the final address is not in fact your home. It is the postal station. But if it were ok for the postal worker to sign we would not have all the reports about having to go to the Lady Lake PO to pick up packages because you weren't at home.

The signature form as posted in the image above seems to say S FitzPatrick in cursive, then printed with some address including a route number. No effort to deceive as apparently the employee did not sign Ed's name. My guess is the rules have changed but if so I'd have hoped the USPS website would reflect the change which makes signature required a meaningless service as there is no proof the package got to the addressee.
That the form posted has recipient's name, with Ed and actual recipient's name with Ed is false. The option for a variation is that someone in a household or business can sign, thus I might sign for a package addressed to Mrs Blueash or a receptionist might sign for a package sent to the Ace Repair Shoppe. The form on Ed's package says Ed signed as the actual recipient. He did not.

I think the value of a signature is way overrated. Have you ever had to sign a touch screen with your finger? I have, and it doesn't look anything like my signature on legal documents I have signed, and it could never be matched or validated by a handwriting expert. So, what is the point?

Well, the tracking form from USPS says "ACTUAL RECIPIENT NAME" was **ME**, E F**** which is separate and different from "RECIPIENT NAME" although it wasn't my signature for the package and I did not sign it. "ACTUAL RECIPIENT should have been the post person. After sitting home waiting for the package and then suddenly seeing it listed as DELIVERED and signed by ME that is what concerned me considering every other signature required USPS package in the last 4 years has been brought to my door. Even stranger was yesterday I has a very small package from Amazon (no signature required), value about $3 delivered to my door by USPS truck and handed to me. Weird.

AGAIN, just to clarify, I have no problem (only concern) with what happened with this specific package, it saved me a trip to LL, it just doesn't look kosher and can open a can of worms with places like eBay and similar.

You are 100% correct wrt to the "value" of the signature but at least you know you entered the chicken scratch .... but had it been ME who signed it saying that I received it and not a stranger who was claiming to be my legal agent and receiving my package for me.

I still need to get down to LL PO and find out if this is a new "covid" exception to "signature confirmation." I was more than willing to give them a blanket release but at that time they said they don't do that because I or someone IN MY HOME had to sign for packages. Currently I don't reside inside that 4x4 box. :D
