Hello, the hotel is obliged to ensure safety during Party A's meal and protect your personal and property safety during Party A's meal. In this case, the hotel security guard had the obligation to stop the fight, but did not come forward to stop it. There is obvious fault, that is, the hotel has indirect infringement. The direct infringer is B, and B shall be liable for direct damages, and the hotel shall be liable for supplementary liabilities (that is, when B cannot compensate, the hotel shall compensate).
