We buy cakes in the store. Knowing that the seller is stupid, I tell her clearly and clearly:
- Give one with potatoes fried, one baked and one with eggs.
She interrupts me angrily:
and ah! The young man! I have a head, what is yours? One with a potato, what else?

Now we call it the “Seller’s Cake Syndrome” – when no more than two words are placed in a person’s memory.
by PS. I checked many times - real, two words - the absolute maximum.
