Hi Mr Montana,
I am sure that there probably is some way of doing this, and someone very clever will come up with a system. That person, I guess, will know about a concept named the Zeigernick Effect.
It’s a fascinating thing - much deeper than the little blurb which follows:
(this is from Zeigernick Effect Explained
Discovery of the Zeigarnik Effect
“Lithuanian psychologist Bluma Zeigarnik observed the effect of interruption on memory processing in 1927. Whilst studying at the University of Berlin, her professor, Kurt Lewin, had noted how waiters in a cafe seemed to remember incomplete tabs more efficiently than those that had been paid for and were complete. This appeared to suggest that the mere completion of a task can lead to it being forgotten, whilst incomplete tasks, such as serving guests a table who had not yet finished their meal, helped to ensure the waiter remembered their order.”…
That was only the ‘discovery’.
It applies to more than waiters. It also applies to music - I can play a song - then forget it after I’ve played it - even if it has been a long session with many takes… It is as if I had never played it at all.
I have a couple of personal examples which I’ve seen with my own eyes: One is:
Couple of years ago (2018) I was through in at the Edinburgh Fringe Festival and we fancied a curry/
We went a restaurant called Cafe India, Edinburgh is mobbed at Festival time so we thought there was very little chance of getting a table, right enough the restaurant was packed out with tourists and we saw people being turned away at the head of the queue, but we stood in line for a good ten minutes just to ask about getting a table. Once we did, my wife asked very sweetly whether we could book a table in an hour or two - as we could come back. The manager, harassed, working hard with hundreds of things going on around him replied to us, “We are full, so it might be a while”, we said that’s okay and he asked “What’s your name?” I told him mine “K. Mister K”. “Okay.” He said “Come back in an hour.” - He did not write my name down and immediately started speaking to another group of hungry people being driven crazy with the beautiful smells…I was sure he would never remember.
We went back an hour later.
I went up to the lectern, just inside the restaurant. Where a junior member of staff was, he said they had no tables… but then from the back of the restaurant the manager who had taken my name came up and said “Hi Mr K, follow me”. I was amazed but knew of the Zeigernick effect and thought it might be that…
Half way through the meal the manager was doing the rounds and we got talking - I made mention of his remembering my name - and he looked puzzled, because he could not remember it… We then got into a wee talk about memory - I told him my interest in the subject. Although I can’t be sure I suspect that this is the Zeigernick effect in action.
Incidentally I remember “Zeigernick” by thinking of a ‘nick’ - (=Prison in UK slang) on the snowy slopes of the Eiger (great big Mountain in the Alps)… the Z I do not have to encode.
Good luck with your attempt - though it seems a bit of a challenge. I’d probably associate each person with a time (encoded as a visual) and one of the things they ordered. But it would not be easy.
