I am, in agreement about how coaches are supposed to act, but the way the rule is written, it leaves little room for interpretation, for example, if a 1st base coach takes a step out of the box to ask the base umpire if he can ask the plate umpire if the the first baseman pulled his foot off of the bag, both coaches are supposed to be confined. if he does this in a respectful manner, there has never been a problem in the past, but could be with some umpires who are more literal than others.
