Reporting in USA Today:

The Soap and Detergent Association is out with an annual study of the hand-washing habits of men and women. The association sent people out into the field to watch the actual hand-washing habits of people (as opposed to what they claim in surveys). It  found that while 92% of people said they washed up in public restrooms, only 77% were observed doing so.

The Turner Field connection? Only 57% of men using public restrooms washed their hands afterward, according to the association. Women did much better: 95% of women washed their hands at the baseball park.

Nobody tell Belle.
