This case is a typical example of illegal operation in the fitness and leisure sector. Based on complaint clues, the Xinghualing District Administration for Market Regulation found that a ski resort, when selling ski tickets on Douyin, made the 20-yuan-per-person locker service a mandatory item, which consumers could not cancel. This act of forcing optional additional services to be bundled with tickets deprived consumers of their right to independent choice and violated the Measures for the Administrative Supervision of Contracts. In the end, the enterprise was given an official warning and a fine. This case clarified that fitness and leisure venues must adhere to the principle of fair trade, and cannot force the sale of additional services under the pretext of consumption scenarios, which has a warning significance for the compliant operation of various sports venues such as ski resorts and rock-climbing gyms.
