A friend of mine moved to New York and had me ship her computer (several boxes) to her via this UPS store. I'd used this place before with no problems. Thanks to some good ol' UPS mixups one of the boxes (the actual PC) was shipped back to Phoenix, back to New York, and back to Phoenix again, ending up back at this UPS store.
Aforementioned friend was understandably mad and didn't want to have to pay to ship it again, called UPS and demanded they pay for it. UPS customer service agreed to and called the manager of this particular UPS store to confirm, but the manager proceeded to freak out, accused the corporate UPS employees of being 'fakes' and trying to rip him off, and held my friend's package hostage, saying he wouldn't ship it anywhere until somebody physically came into the store and gave him money to do it.
So I went in there and took the package to FedEx instead. (Which also sucked, but not nearly as much)
Maybe he had good reason. Maybe he'd been ripped off by fake corporate UPS employees before. Either way, he came off like a total nut and pissed everyone off.
