We were high-spirited and thought nothing of
working out of a phone booth,as long as we were
doing the good job.
这个句子好难好难，请各位高手指点

同意not4fun。

Out of 有从…里面的意思，在这里就是从电话亭里面

译文：
We were high-spirited and thought nothing of
working out of a phone booth,as long as we were
doing the good job.
我们兴致勃勃，根本不在乎在一个电话亭里工作，只要把事办好就行！

看过一篇文章，说几个人要办一个公司，开展一项大事业，并兴奋地告诉其中一人的姑妈（姨妈），姑妈问：“你们有办公室吗？”她说: “我们就在电话亭里工作。”
“Do you have an office?““No, I'm gonna work out of a phone booth.”

无意与各位抢分，还是那句话，只想让提问者得到准确的答案。望理解。
