Your most embarrassing moment?

I'm sure all of us have that embarrassing moment. But since it is embarrassing to post it here, I would probably post this near-embarrassing moment that I had experienced.

When I was hired as technical consultant of an organization in the movie industry, I was at once immersed in meetings because of a hot issue about their new website. In one meeting held in a restaurant, I was seated beside 2 bigwigs in the industry, a lawyer and a producer. We were all holding the menu. The lawyer said he would go for sea bass to which the producer agreed. I thought I heard Chivas (Regal is an expensive whiskey). I was wondering why they would have a drink that early. When the producer asked me what I would order, fortunately, I thought about the food and maybe I would order the whiskey later. And when the waiter came, that's when I realized that the 2 guys were ordering Sea Bass, the fish.
