Radio 4 documentary about couriers

im not sure if this is the same documentry i listened to on iplayer. the one i listened to was a bunch of people moaning about how slow buissness was. me and my friends dont talk about our work togather becuase its fucking boring, so why do i want to listen to a bunch of strangers who deliver packages.

One of the reasons why lots of people on here liked the programme (in another thread where we talked about it), is that at least two of the interviewees in it sometimes post on this forum and are well liked due to their personable natures.
