Frugality Frustrated

I like to be frugal, not only with my resources but also with those of my employer, so I printed off (greyscale, fast) my 12 page student workbook on the reverse of some obsolete letter-headed notepaper – so far so frugal – however when I took it to be copied (six sets needed) instead of a slim booklet of six back-to-back pages the operator managed to produce a twenty-four page single-sided document of which every other page was blank apart from the redundant letter-head of a defunct college; so frugality was frustrated to the extent of an extra 108 sheets of A4 (albeit I will recycle 72 of them back through the printer).
