I'm sorry to hear that. That's unusual. I'll look into the matter at once. 很抱歉，这很不寻常。我立刻去调查。

Anyway, I've lost my confidence in your hotel. Please cross the crab off my bill and I'll leave now. 无论如何，我已对你们酒店失去信心，请在账单上剔除这个菜，然后给我结账。

Please be assured that we will look into the matter. Our chef is very particular. 可以叫您保证我们一定会追查此事的。我们的厨子很不错的。
