A letter from civil engineer and transportation pioneer Isambard Kingdom Brunel (b. 1806-04-09, d. 1859-09-15) to the owners of Swindon Railway Station, December 1842:
Dear Sir,
I assure you Mr Player [the manager] was wrong in supposing that I thought you purchased inferior coffee. I thought I said to him that I was surprised you should buy such bad roasted corn. I did not believe that you had such a thing as coffee in the place; I am certain that I never tasted any. I have long ceased to make complaints at Swindon. I avoid taking anything there when I can help it.
Yours faithfully,
I K Brunel.
