Example of minimizing measurement cost~
  Dim sum selling in Chinese restaurant

Some of the Chinese restaurants in Hong Kong set a standard price (eg. $10 each) for all dim sums at their restaurant. This is actually a method of minimizing the measurement cost.
From the restaurant's point of view, it can help reducing the measurement cost. Under the standard pricing, whether the consumers eat large dim(大點), median dim(中點) or small dim(小點) the price is the same.
So, when the restaurants check the bill, the only thing that concerns is the number of dishes ordered and the standard price. Therefore, much measurement cost is saved.
Also, as the marginal cost (MC) of different dishes is different, it will be very costly for the restaurants to distinguish which dim it belongs to. If there is a standard price for all dims, much measurement cost can be saved.
Besides, for some dishes the MC of producing them may be higher than the standard price whereas the Mc of producing other dishes may be lower that the standard price.
Therefore, restaurants will only adopt the standard pricing only when the measurement cost saved and the economic reant of some low MC dishes (< standard price) are enough to compensate the loss in revenue incurred by selling some high MC dishes (> standard price).
