What do you do?

[Little Jimmy]

When your're the field ump, what do you do when you see the plate ump ignore the courtesy runner rules? Today I worked with a guy ( a good guy overall ) who kept no record of who courtesy ran for who and as a result one runner took the place of both the pitcher and the catcher throughout the game. I paid attention because the coach tried to do this when I was working plate for his team last year and I corrected him a few times. I don't really know where the boundries should be when field guy sees plate guy misinterpret/ignore things. And tomorrow I work with someone else who will do the same thing ( he did it last year ).

I just wonder the proper etiquette is. I have mentioned it in the past ( in between innings..."hey, didn"t that girl run for someone different last inning?") but I usually get something like "it really doesn"t make any difference" and we move on.

It bugs me but I don't want to be a pain in the *** to my fellow blues. Any comments?
