I am convinced that all shops have mischievous elves. I started a spreadsheet many years ago to keep track of seldom used items. It now has 9 sheets and is hundreds of lines. I can find almost anything . Whenever I am looking for something that is not on the sheet I am sure to add it once I find that place I put it that made perfect sense at the time. The old noggin ain't what it once was and the spreadsheet helps fill in the holes.
