It is definitely illegal for people who contract canteens to charge benefits, and they can definitely refuse. But after refusing, you need to weigh whether you can still contract the operation. If it doesn't affect your normal business, you can refuse it directly. In fact, investment is risky, so investigate more when you invest next time. If a contract is signed, it should be handled according to the specific contents of the contract. It depends on the agreement between the two parties. If negotiation fails, it can only be settled through litigation. It is still suggested that the two sides negotiate calmly to see if there is the best solution before taking other actions. Communication is the most important thing, but don't be suppressed by power. I hope my answer is helpful to you.
