Accepting a complaint in Japanese
At Kissa Hotaru, a customer says the blend coffee has gone cold. Masako has already poured a fresh cup, but she lets Leo handle the complaint.
Leo needs to acknowledge the problem, apologise formally, and explain what he will do next.
These phrases suit a real service problem: own the missed check, offer a replacement, and prevent a repeat.
Listen for the humble いたします and the careful offer to comp the drink.
By the end of this lesson

Scene — a cold blend
A customer at Kissa Hotaru tells Masako that the blend has gone cold. Masako has already poured a fresh cup and asks Leo to handle the response.
