How do you handle batters time?

On the use of 7-3B, we need to remember the admonishment given to umpires on enforcement of this rule, which putting it in everyday language and adding to it based on my personal reading between the lines says...

"This rule is to prevent delay of the game. Giving warnings is preferred, but the strike call is there for particularly egregious situations. Don't be picky."
