[Back In The Saddle]

I have seen this happen a couple of times in the past year, but not in any game I was working. In the instances I witnessed, the act did not appear to be directed at the official or to the crowd, either of which would warrant a T from me. I like the suggestion of the warning about keeping the shirt tucked in. It should get the point across without being heavy handed. However, the act is a sign of frustration, which should not go unnoticed by the officials.
