毎度: repeated questions and a shop owner's thanks
Read 毎度 in receiving the same question every time and in a shop owner's conventional expression of thanks, without inventing visit or purchase counts.
Receiving the same question every time
毎度同じ質問をされるので答えを紙に書いた。 reports receiving the same question every time and therefore writing down the answer. 毎度, read まいど, describes the recurring situation of being asked the question.
書いた supplies the past action of writing the answer on paper. The repeated event is receiving the question; the sentence does not specify how many answers were written or whether the questioner was always the same person.
毎度 in a greeting of thanks
「毎度ありがとうございます」と店主が頭を下げた。 reports the shop owner saying 'Thank you as always' with a bow. 毎度 appears within a conventional shop greeting expressing thanks.
Unlike the first situation, this sentence centers on the owner's thanks and greeting. The wording does not provide a count of the customer's visits or purchases.
Identify the repeated situation
Identify what 毎度 connects to rather than replacing it with a precise frequency. The first example describes recurring questions, while the second conveys the owner's continuing thanks.
Keep the person receiving questions separate from the shop owner expressing thanks. Reading the greeting as a report that the owner repeatedly asked the same question would change the second scene.
How does 毎度 relate to repetition in the two examples?
Show the answer and why
The first describes receiving the same question every time. The second is the owner's expression of continuing thanks. Neither supplies the customer's visit or purchase count.
