I kind of used that technique when I was working as sales for small gastronomy single-use plasticware. I went to a customer without notepad, he was telling me what he needs like 20-30 items with amounts, and the way I was able to remember that list was because at the time person was telling what he needs I was imagining place in the truck where I had what he needed. So only reading that story I realised that I was using some technique that I never heard before.
