I remember that a friend of mine who was working as a supermarket cashier told me that she had once made an embarrassing mistake during her apprenticeship. I stupidly blurted out, "You mean you have to do an apprenticeship for such as simple job as working at a cash register?"
還記得有一次當超市收銀員的朋友談起她在實習時所發生的糗事，我不經大腦思考就說出：「收錢這麼簡單的工作居然還要實習！」
