(1) Pay attention to personal hygiene. Dress neatly and without contamination, and keep your head, hands and other parts clean. When providing services to customers, behave appropriately and naturally. (2) Familiar with dishes and drinks. When customers don't know much about dishes and drinks, they should give detailed explanations in time and give reasonable suggestions for ordering food appropriately, and they should not ask questions without knowing them. (3) Respect the choice of guests. When customers order, they don't repeatedly recommend dishes, drinks, etc. that customers don't order. Respect customers' religious and ethnic habits, and take the initiative to ask customers who come to eat for the first time if they have any taboos or other dining habits. (4) Warm and meticulous service. When receiving a guest's order, carefully record the number of visitors and the meal time, and ask if you need a smoking area or a seat with a good view; When guests enter the restaurant, take the guests to their seats enthusiastically and actively; When providing services to customers, we should follow the principles of female guests first, male guests first, guests first, masters first, elders first, children first, adults first, etc. When the guests leave, remind the customers not to forget their belongings, and thank them. Welcome to visit again. Don't pick your nose, ears, take off your shoes, change clothes in front of guests, and don't give directions or pull familiar guests. When customers order, they can introduce and recommend the special food of this restaurant appropriately. When the dishes ordered by the guests are enough, they should take the initiative to remind them to avoid deliberately inducing customers to order too much and causing waste.
