2. 办信用卡防贼
学生之前往往用现金买饭,学校准备推出信用卡来防贼,这种信用卡会有学生的签名和头像,所以食堂里的员工可以辨认出学生来,减少贼。But this measure will not work, why?
有很多可能: a. 家长不喜欢用信用卡,因为要还钱,学生每天的现金数量有限好控制,但信用卡无法控制 b. 食堂员工无法完全核实签名和头像 c. 一旦被偷走,会损失比先进多的财产 d. 贼的数量和是否用现金或者其他支付手段无关

B: Did not considerfactors other than the bans that may affect the tourism growth
