Means of payment have been around for a long time, but they have always been in the form of goods exchanged, or services paid for in goods. You could also pay in a promissory note. As early as the 3rd century BC, you could pay in the form of a lump of metal weighing a few grams.

But it was around 600 BC that the king of the country of Lydia (formerly Turkey) introduced a coin containing precious metals such as silver or gold. There was also a stamp showing which precious metal was contained and how many grams. The stamp also showed which authority had made the coin. This gave the coin an actual value.

With this, the requirement for the quality of goods and services changed, but mainly services in the form of the performance of service and the quality of food if you bought cooked food.

The demand for service and quality instead of quantity was high but then the few newly rich who had access to the new coin knew where to go to get what they wanted.

As the number of newly rich increased so did the demand but now their attitude and courtesy deteriorated, so much so that the entrepreneurs lost their joy and felt depressed and over time lost their pride. This affected the non-newly rich who were often treated badly by the entrepreneurs and their staff, despite the fact that they were the most loyal customers and were the ones who paid the most, but then with other means of payment than the precious metal coin.
