Years ago, I was the assistant to the Executive Administrative Assistant in a company I worked for.
I often had copy machine duty, making dozens or sometimes hundreds of copies of various business docs.
Since I had nothing better to do while making the copies, I would often read through the documents.
After several occurrences of me bringing back several completed copy sets and mentioning that I had found spelling and/or grammar errors she finally thanked me and said, "in the future, would you please proof-read them first and then bring them to me before copying?" : D
