Recently, a colleague returned from a business trip to Germany and raised a puzzling question. Due to his work schedule in Dortmund, he could only go shopping around five or six in the evening, but he found it difficult to do so. As soon as the clock struck 6:00 PM, even if the shop was crowded with customers, the staff would politely inform them that it was closing time. On weekends, most shops are not even open. He was confused: "Doesn't market economy say that the customer is God? Isn't making a profit the ultimate rule? How can they possibly drive 'God' out of the door?"
It turns out that in the eyes of Germans, extending operating hours might satisfy customers and benefit owners, but it would infringe upon the interests of the employees. The same applies to weekends; longer hours would mean workers' rest time could not be guaranteed. While my friend was bewildered, what we were actually witnessing was a reflection of labor relations in a mature market economy: customers are God, and employees are also God!
