They were tipped off. They knew your pickup time.

有人向他们透露消息 他们知道你的提取时间。

So I'm just going to skim this quickly and it says, if residents are unable to abide by the pickup times, they can request a recycling card in order to transport recycling refuse to the ecological island.

所以我会快速浏览，它说，如果居民无法遵守回收时间，他们可以要求一张回收卡，以便将回收垃圾运至生态岛。
