Number of Warm-up pitches?

[illiniwek8]

This might be kind of nitpicking, but here is my question/situation. It is the 4th inning and the coach is out to switch pitchers. His pitcher gets to his 7 warm-up pitch and the catcher decides to run to the dugout to fix a bandage which he had on his finger. The coach comes in to finish his pitchers warm-up and procedes to take extra warm-up pitches while the catcher is being attended to. I (thinking I am doing the right thing) tell the coach that his pitcher has had his warm-up pitches and don't allow him to continue. Now that I am writing this...it sounds kind of bad what I did....was I wrong in doing this? This was the coach's 3rd pitching change and the catchers second time having to go to the dugout to fix a bandage on his finger.....the game was dragging and I wanted to move the game on. I also thought it was not fair for his pitcher to recieve extra throws because the catcher decided to take off after the 7th warm-up pitch. Any feedback on this would be greatly appreciated.
