I'll add another point...
Never toss the ball to the catcher - I always make it a point to HAND the ball to the catcher. Why, because I don't want them to toss the ball to me. Why, because I can't catch, especially with an indiclicker and a mask in my hand.
For me, it's a respect thing as well as a rapport builder with F2. You know F2 really has a clue when he not only hands the ball instead of flips it to you, but the good ones will prop the ball up on the edge/tip of their mitt and "serve" it to you. Now that's what I call RESPECT.
For those of you who don't know what I'm talking about, you probably think I'm crazy. But sometimes, it's just the little things that people do that says a lot about their professionalism.
Another good one is when you turn to the ball boy and signal/tell him you need 3 baseballs. Then, another foul ball goes into the stands and rather than bringing out 3 balls, he now gives you 4 (to account for the foul ball). Now that's a ball boy who is paying attention or what I call, "has a clue".
Like I said, it's the "little" things
