If you were a dishonest person and wanted to teach him a lesson you could always report it stolen. Doesn't UPS have to cover it when a signature is required and they don't get it? Unless he's a dishonest person and signed for it himself.
After I told him my shock of not having to sign for it because of the expense and the fact that UPS online stated signature was required, he asked for my last name and input it into his system. Either way I still didn't sign for it, and if I were not home he was going to leave it at the doorstop with 2 of my other packages (that didn't require signing). Not cool, UPS. My house has been broken in to before so I wouldn't put it past anyone to steal from my porch.
Still experimenting with my brand new 1.2. Getting somewhat nervous because I'm finding that my focus points are not very sharp, even with faster shutter speeds.
