Tuesday night I filed a complaint online about what happened in the previous post. Today I received a callback from, I assume, the manager of the local post office, Midwood branch, on Coney Island between I and J. In no uncertain terms the manager informed me that my beliefs are my problem and they will not change their policies to suit me. He told me that not being able to sign because of a Jewish holiday is not their problem but mine. I asked him what would happen if the addressee would have a broken arm. He told me that he'd have to have someone there at the time of delivery to sign for the package. That's right, if you're disabled, too bad for you. It's your fault you can't sign for the package and the post office will not accommodate you because maybe you should have took this into consideration before deciding to become disabled.
I emailed Simcha Felder, email@example.com, and Michael Nelson, firstname.lastname@example.org, regarding both incidents. If you live in Brooklyn and don't want the same thing to happen to you, do us both a favor and send them an email, referencing these two posts, and ask them to change the USPS signature policy.
