I really agree with this. Your exact example -- every detail -- happened to me a few years ago. I was offered a ~50% raise without really seeking it out. I went to my boss (with whom I had an excellent relationship) and explained the situation. I got the raise that day, and over two years later I've continued to get great raises/promotions, and it has become the best job I've ever had. It is important to note that I was doing really important work at the company. I was probably not considered a "normal" employee.
