In January 2020, Xiao Wang from a university went to visit Shanghai Disney with her friends. But the staff at the gate stopped them because they carried snacks and drinks. “You can't bring food or drinks inside. You have to throw them away, or you cannot go into the land.” “Why? I think I can't do that. We can't waste food.” Said Xiao Wang a little angrily. “It's a rule, Miss.” the man answered, “You can eat them up or keep them in the locker (寄存柜). But it costs 80 yuan a day.” “The rule is not reasonable (合理的).” And you didn't tell me the rule when I bought the tickets. Xiao Wang thought that Disney just wanted to make people buy snacks and drinks inside and make money. However, the staff said they just made the rule to make Disney clean and tidy.
