This is an old favourite that I found today while doing some spring cleaning in my atticesque cupboard. I am transcribing it from an old handwritten version!
This ‘Letter of the Decade’ was sent to the Scotsman in 1987:
“Sir, I note with interest that you have published my letter of 13 June three times (so far) this week. I’m pleased that you like it so much but if the letter is to become a regular feature in the Scotsman, I’d quite appreciate a small fee by way of acknowledgment. May I add that I approve of your use of different headings each time the letter is published. This helps to prevent it becoming too stale or repetitive. Let me know if your readers grow tired of the letter and I’ll write you a fresh one.”
Unfortunately, they omitted his name, but thank you whoever you are.
