在一次访问北卢安瓜的时候，我偶然碰到了萨蒂·贾斯蒂斯，那时他正当游猎向导。
On one of my visits to North Luangwa I came across Sunday Justice who was then working as a safari guide.
单个的访问不只是意味着一些偶然的页面请求；它还意味着在访问期间有一个持续打开的连接(带有等待线程)。
A single visitor doesn't just mean a few incidental page requests; it also means an open connection (with a waiting thread) for as long as the visitor stays.
或者，存在一个偶然事件让您的客户不满意，然后通过频繁演示来达到更好地访问您的客户。
Or, point out an incident in which your customer was not satisfied, and ask for better access to your customer through frequent demonstrations.
