YSK: if you're used to getting a deal or discount from a couple employees at a place, that doesn't mean you are entitled to it everytime, from everyone. And by saying you are used to getting said deal to a manager, you are screwing over the employees who have been hooking you up.

YSK：如果你習慣於從一個地方的幾個員工那裏獲得交易或折扣，這並不意味着你有權每次都從所有人那裏獲得。如果你說你習慣於從經理那裏得到上述優惠，那麼你就是在坑害那些一直爲你提供服務的員工。
