A waste of space thriller..!

When I worked for British Rail back in the 80s and early 90s, one of my jobs was to look after the office photocopier; it was a big floor standing thing and was always needing more paper and toner etc.
Someone made up this silly drawing and pinned it up above the machine, which we all thought was so accurate..! I just found a copy of it whilst going through some old documents for filing/shredding so thought I'd share..!
