Everything on the way home-something unpleasant

Today, I am not willing to go home because a customer calls me to tell me that a serious problem has occurred in the system. I have to pay less for a certain order. On the phone, she knows that my habit is to let her immediately make a test ticket, then I will analyze the cause, and finally decide whether to go to her, so she told me to go without discussion.

I don't know what the problem is. I just passed here.

When I entered the sheet at the company, the result was less than that of manual work. I had to set the sheets one by one based on the formula. The result showed that the sheet was directly pressed out of the White Paper, in the Basic settings, she didn't have a thorough understanding. For a layer of paper, she didn't set the length of life and tongue inserting, which led to the decrease of the calculation of the Board.

Knowing the problem, she became much more secure. Although the problem is not my problem, the loss has already led to (the paper tray is not big enough, so I had to discuss it with the customer and turn it into two pieces. I had to pay half of the goods first, which is too much waste and a waste of work hours, reduced external image ). Here, I don't have any problems. The biggest problem is that I don't have a good relationship with her. I don't know whether my system has reduced her role or is my real person, she and I will have a quarrel. In this case, we cannot communicate well.

I am really worried about whether I will continue to take responsibility for maintenance in my software lifecycle. I really don't want to maintain the amount of money the other party spends. Every day, I worry about a place that she never imagined, or she wants to come up with a self-righteous operation method, and then the system causes losses. Or I only provide telephone and internet maintenance, So that I cannot see her.
