But if you work at an AD agency or are a sales guy at an online publisher getting ready for a meeting with a big brand, it helps to know what display ads they are running.
但如果你工作在一个广告公司或者是在一个在线出版商销售的家伙得到了一个大品牌的会议做好准备，这有助于他们了解正在运行的展示广告。
An AD agency that won't buy ads, a consultant who won't buy consulting, and a waiter who doesn't tip big-it's a sign, and not a good one.
一个广告商不买广告，一个顾问不咨询事情，和一个侍应不给多的小费——钱是一种符号，除此之外，不是什么好东西。
