Management of enterprise canteen

Our company's practice is: individual contract management, employees swipe their cards to eat. Those who don't eat cauldron dishes will be charged extra for cooking. Every month, the company fills in a meal allowance for everyone's meal card, stipulating that the number of times of swiping the card to eat in the canteen should not be less than n times per month (to ensure the business of the canteen, otherwise the contractor will be difficult to operate because there is no business), and the subsidy for meals below n times will be cancelled next month. The unused balance on the card is not allowed to be returned in cash. There have been no major problems in our canteen this year.
