You Pull Into a Japanese Gas Station and Three People in Uniform Run at Your Car.

Why this phrase

A rural full-service petrol stand. Hana plays the attendant at the driver's window, Kofuku plays the rental-car tourist who needs one sentence to get a full tank. The attendant opens with 「いらっしゃいませ。何をお入れしましょうか？」 and Kofuku answers 「レギュラー満タンでお願いします」. Accuracy guardrails from the Japanese verifier: staff speak keigo to a customer, so do NOT write the attendant saying 「何にしますか？」, which is peer-level. The formula to teach is fuel type plus 満タン plus でお願いします. Real-world note to reflect: at a full-service stand you usually volunteer this through the open window right after 「いらっしゃいませ」 rather than waiting to be asked. Payment is the natural next beat, 「現金でお願いします」. This is a travel-logistics video, so the cta beat must speak AND show the trip kit hub instead of the phrasebook.
