I just had a hell of a day being turned away by stores who couldn't sign for a high-value-insured guitar I needed to ship today and had to catch a UPS driver in the lot to take it. I've never experienced this issue before shipping anything high value over the last two years.. Is this new? Are UPS store employees so untrustworthy that they can't be allowed to sign for something valuable? Have I been duped? irritating..
