Your App Says It Means "Nice to Meet You." People Say It to Their Dentist.

Why this phrase

One scene, landed hard: a small Kyoto cooking class. Hana plays the host, Kofuku the visitor who fires 「よろしくお願いします」 as a greeting and thinks he is done with it. Then he hears it twice more in five minutes. Hana opens the class with 「今日はよろしくお願いします」. She slides a knife and a board of vegetables over and says 「じゃあ、こちらお願いします」, because she is handing him a JOB, not an object. Then Kofuku passes the pan to her and uses the full phrase himself. Direction matters: the person ENTRUSTING the work says it, never the person taking it on. The bust is precise, not a fog: greeting is one of its jobs, not its meaning. The invariant is a forward-looking request for good treatment, which is why it lands at handovers, requests, sign-offs on a meeting, a new job, and yes, the dentist's chair. It is NOT a parting greeting, so never let it stand in for さようなら. Keep the correction warm; the viewer was not wrong, just half-informed.
