I know someone that bought an expensive Mezzie case, from a retailer, and it was supposed to have a signature because he lived at a busy intersection and there was no place they would be able to put it without it being seen. That was told to the seller and was in the comments on the packing slip.
They dropped it off in the middle of the day, no signature nothing. So he took it inside and called the seller to tell them that UPS said they delivered it but it was no were to be seen. They settled with UPSs insurance, since it had it and sent him another one.
Same thing happened they dropped it without a signature.
Signatures mean nothing to most shippers, especially CP.
Nothing says loving, like a head shot!
