when和once的选择疑惑
If customers want to try the “take in” experience, they can use the Wolt app, just as they would from the comfort of their own homes. When they order and pay for their meals, all they have to do is to wait for someone to deliver it to the restaurant.
老师，这边为什么一定要填once,如果填when,可以吗？ 有什么逻辑错误吗？

网友是指红色位置的连词吧。
when 只表示“时间”，而once 既可以表“时间”，也可以指“条件”，这两者意思兼而有之。
就本句意思而言，选用once 好于when，但用when 也不能算错。

Both "once" and "when"can be filled in the blank given by the sentence .
