My sympathies on the lost lens DXphoto. I hope between the shipper & UPS you get another. A relationship with the driver can be your best tool when dealing with UPS- but I guess in most areas there's more than one driver delivering to you.
In rural areas Fed Ex Ground can be quite the opposite- unwilling to deliver to me since I live too far off the beaten path. The last Fed-Ex Ground driver on my route would simply not deliver to me. I'd get a call saying that he'd tried but nobody was home, so it was at the Fed-Ex location awaiting pick-up. One last time I tracked the package, saw it was on the truck for delivery as of 6:10am and stayed home waiting. I re-checked at noon and saw that it had been returned to the Fed-Ex location at 9 am, as undeliverable. I've been there to pick up packages many, many times that they simply would not deliver- it is 45-50 minutes away. We've since got a new driver, and more often than not I get a call asking me to meet him at the Post Office in town. Very annoying, when one ends up paying for shipping only partway to the destination.
DHL will only deliver to my area once a week- an 'overnight' repair to my laptop took ten days.
Both my current and previous UPS drivers and my current Fed-Ex Express driver are top-notch, we have arranged safe locations for packages should no-one be home and if I'm expecting something I'll stop if I see the truck in town to save them the ride down my long dirt road.
