I had a bad experience with UPS recently. It was my new Gitzo from B&H, and it was signature required, and my wife was at home. I come back to see no tripod, and checked status to see 'delivered'. I live in a very secure apartment complex (only doctors and researchers) so I was very surprised as to who else would sign for a large long package clearly not in their name? Called UPS, they said they'd fix it right away- and to their credit they did. I got a call 2 hours later saying the driver had gone back, retrieved the package (from where?) and re delivered it (in my absence, since I was out). It was a bit worrisome, especially since it was a Friday evening and I couldn't even reach B&H.
What worried me most is that the driver delivered it incorrectly in an apartment complex which has clear apartment numbering and where he/she delivers everyday!
