I've seen some real lazy postmen. I'm a solo, so I'm not always in. I've seen them walk up to my door and leave a tag without trying to open it because they assume I'm gone. Tbh I don't really care. If you send me something with signature required, it's probably not something important if I'm not expecting it. If I haven't received an email "were sending the check usps express, here's the tracking," I'm not going out of my way to figure out what it is or to run to the post office up get it. If it's important, they'll email or call.
