終わる to mean closed shop

Question

Is it a natural or at least used way to say "closed" like in that example, using the verb 終わる ?

• A : 今7時ですが、スーパーは終わりましたか。
• B : いいえ、8時まで開いているはずですよ。

Answer 1

Yes, it's used, but 終わっていますか may be more natural since you are concerned with the current state rather than the past event. 閉店していますか is a stiffer way of asking the same thing (preferred in emails etc), but 終わっていますか is perfectly fine in speech.
