The alarm bells should have started ringing here but we were excited to have arrived so paid up front. 5% charge for using any type of card which was never mentioned.

这时就应该响起警铃阻止我们付钱的，但是我们还是在前台付了钱。其中5%是收取那些不知道什么卡的使用费的。

If a referee only got to slightly rub his or her temples, would ringing up a charge lose its appeal?
