first, we should distribute leaflets to publicize it when we start business at the beginning.
second, issue bonus cards, that is, take bonus cards to your hotel for dinner and drinking, and the price of vegetable rice is lower than other places.
thirdly, you should give some money to those customers who often come to eat, as long as he brings guests. The more frequent he comes, the more people he brings, the more expensive he eats and drinks, and the more your family pays him.
then, on holidays, you should also hold festivals. Sometimes there will be some sales promotion. Fourth, < P > Buy some cheap products that are about to expire and give them to regular customers.
you can also send some small favors to customers every time you eat.
I hope you can understand my personal thoughts.
