If they said yes, we gave them another one, and when they finished, we asked them, "Do you want to build another one?" for $2.40, $2.10, and so on, until at some point people said, "No more. It's not worth it for me."
如果他们同意的话，我们就再给他们一个。 等他们拼完之后，我们又问， “还想再做一个吗？” 分别付给他们 2.4 美元，2.1 美元，依此类推。 直到人们说 “不用了，已经不值得我去做了。”
