PH waiter is a new profession, which is essentially a profession that provides catering services. PH is the abbreviation of pH value, so this kind of waiter can be said to be a service person who "adjusts pH value". They can usually give advice on catering and nutrition, such as how to balance the pH of food and give advice when customers order food.

The responsibility of a PH waiter is not limited to giving advice. They may track customers' ordering needs and menu choices during the service, ensure that the dishes meet food safety standards, and help customers solve any problems. In addition, they also need to know how to provide customers with a healthy diet, overcome eating diseases and control their weight.

The role of PH waiter should not be underestimated. For people who pay attention to health, the advice of the PH waiter is valuable. They can help customers better control their eating habits, improve their nutritional value, prevent health problems, and make customers enjoy their dining time more comfortably and healthily. The PH waiter can also provide answers to questions about harmful chemicals, food additives and pesticide residues. In a word, PH waiters are playing an increasingly important role in the catering industry.
