Is it a pleasure to have customers from afar? Alas, how can I get it?

A few days ago I heard that a customer was here, and the company made another mark. It's a pleasure to celebrate. We are very glad that they have come because they have given the company the opportunity to develop and bring wealth management. As a member of the company, I'm naturally happy.
Now we are switching to the topic: however, we are not at ease with our project. If you are working on a project outside China, you can only add another troublesome after-sales service. Two days in advance, all technical staff of the company dispatched to cope with this inspection. I don't know how these people arranged in the company. Since I went there, I should inform you in advance, and I will not be notified at half past seven that day, so I should go back to the company from where I went to work, on the road, the company keeps on calling for help. What have you done? Will this happen one day in advance? In fact, the most profound feeling is that the more you say, the more flaws you have. This is what leaders tell you. It makes people feel sad and hard to lead. How can we do this? Can we only do this? The crux of the problem is obvious, but there is no one to worry about, no one to do.
