Talking about UPS service, when I was living in Humble, Texas - a town north of Houston, the UPS man also lived in my neighborhood a few street over...he also knew that I often worked late at my job, so he would take my packages home and deliver them after hours, when he knew i was home.... I didn't know him personally, but he took care of me.
At my job in Houston, I often handled letters of credit that ran into 7 figures... I would handle the negotiation of the documents, then needed them delivered to the banks down town. I always used FEDEX as they were best at handling sensitive documents like the LC's... My office was for a while at the Airport, then later out on the 610 loop around Houston and near the ship channel... the packages with the million dollar documents always went to Memphis then back to Houston for deliver... fortunately, I never had any go missing, but also always struck me funny that a document destined downtown from my office, a distance between 10 to 12 miles, always made a trip to Memphis first. Some of the documents went to banks in other cities, like New York, San Francisco etc... those I could understand making the trip to Memphis, but 10 miles to downtown Houston?? 'Course I could have used a local courier, but they weren't near as reliable as FEDEX.
When FEDEX first started up back in the '70's. everyone said the concept would not work... now all courier companies use that concept to handle documents.
