When you see the things that some people do, or the great lengths they will go to to get something they need, you may consider it all to be a little extreme. You could express this idea by saying something like:
"Was it worth all that time and energy?" or,
"That seems like hard work to me!"
In this case, it may ahve been either an economic or a time-based decision that led to this marathon photocopying session.
他の人がしていることを見たり、必要なことをするのにかかった時間の長さ
が分かっていると、そのことが少しやりすぎに思えてしまうかもしれません。
このように言って気持ちを表現できます。
"Was it worth all that time and energy?"
かかった時間と手間を考えると、それは割りに合っている？
"That seems like hard work to me!"
そのことは私には大変なことのように思えます。
この場合、このマラソンのようなコピー機のセッションになったのは、
経済的又は時間ベースの決断だったのかもしれません。
