In the 13 years I lived in the US, I saw the postal service change. It was a horrible, rude bureaucracy when I moved there; and I saw the reengineering at work in the last few years. Counter staff were actually trained to smile and be nice to customers (and those who could not be converted, were sent to back offices where they could “go postal”). You stood in a line, staff would come up to the line with handheld devices to serve customers with minor needs such as a sheet of stamps, shortening the line for people with complex problems that had to be dealt with at the counter. They started selling wrapping paper and tape and creating spaces for people to wrap gifts according to USPS rules.
