It's a difficult world now a days with so many things being delivered and so many carriers. My biggest problems were when I was living in Austin and they were constructing new McMansions across the street from my little bungalow house. The local UPS driver took it upon himself to demand delivery in person with signature on almost anything that was shipped, and the sender/seller didn't require this. I couldn't be home at 3 in the afternoon which seemed to be the only time that delivery was ever made and I had to take a bus and transfer to another bus on a Saturday to go get the items. I complained and was told that the driver had the option to only deliver in person if he felt the packages would be in danger left unattended. I finally asked the dispatcher to sort of sound him out and see why he felt they were endangered. I was told that he felt that because there were "Mexican" workers on the building across the street the packages were in jeopardy. This really really pissed me off as it was pure racism, any danger was unfounded, and there was never a problem of any nature with the construction going on across the street for a period of a year and a half (someone bought the entire other side of the street, hauled off the bungalows and built 8 McMansions) other than the noise problem of construction. I just did my best to not use that shipper until I noticed one day that the drivers had changed, a Mexican-American driver, nicest fellow ever, got this route and everything was improved.

It's always PEOPLE and their behavior that gums the works.

The answer to your question how to handle this behavior is to EXPOSE it.
