the electricity fee for catering has been increased by the loss of electricity, which should be increased. Because there are many electrical equipment used in the catering industry, such as air conditioners, refrigerators and lighting equipment, these equipment will produce a certain amount of electricity loss in the process of use. Without electricity loss, the electricity bill will be lower than the actual use, which is not conducive to the electricity management and cost control of the catering industry. Therefore, the electricity fee for catering has increased the loss of electricity and should be increased.
