MM, You think too much la. If I were you, I would worry about the fees or arguments until I was told to come back. Maybe they can do the test with the 1ml blood. If they did call you back, yes, of course you can argue about the cost.
不一定。这种事情,一般都是某个经理某天消化不良的临时起意,通常不会形成该店的 内部店规得。下一次,换个小二,或者是另外个值班经理,大概率就啥事没有了。但是 ,有内部店规的店面也遇到过。另外,毕竟这个promo的条款里确实说明 one per customer了。只是没有在POS上hard coded。也许未来会hard coded。
