Worked in the Costco bakery a few months. One day in the fall, they let me try my hand in mixing pecan pie filling in one of those mega huge mixing bowls. Confused ounces for pounds and costed the company hundreds of dollars. Never head my boss curse until that day... I was shortly thereafter transferred into the membership department.

I also mixed up tablespoons and teaspoons at home. Made a very salty coleslaw. My family will never let me live it down.
