fan too close to the bench?

[SC Ump]

If I can't tell if it's coming from a fan or a coach, then I definitely ignore it.

Case in point, a coach after a half swing in a big high school game last year: "Ask if she went!!! Ask is she went!!!" Not sure who was yelling, I ignored him. I did this mostly out of habit. I did not even think about looking toward the dugout. Neither the catcher nor the pitcher requested this of me. I just stood there. After a few more yells and after the pitcher got in position but then moved off when the same voice yelled for her to step off, I realized what might be happening. I asked the catcher if that was her coach asking me to check, and when she said it was, I then checked.

Perhaps you might not want to go quite that far, but you asked the opinions of others and that is how I do it. If I'm not sure it's griping from the dugout, I pay no attention. If I'm sure it's griping from the dugout, I usually try to ignore it anyway.
