Faxing... So very convenient!
We have to personally take the paper orginals to various offices around the city, wait hours in a queue, get another paper document, go make copies, assemble another folder and go to yet another office/institution.
A couple of jobs ago one of my colleagues went to work with a Japanese partner for a few days to do an integration. Apparently they had to import a bunch of data and one of the Japanese employees, who seemed to have an axe to grind, printed out pages and pages of a spreadsheet and handed it to my colleague. Whenever my colleague asked him to just send the file, he pretended to not understand. In the end they had to OCR it but at least it was a story.
Don't forget when your coworker prints out a memo, asks you for edits on the paper, then you go in and edit the virtual document.
