Starting a game

[tskill]

Am looking for opinions on how to handle the following situation:

Background: High School game, NFHS rules, game time start is 4:30pm. Show up at 4:15pm on the field to inspect bats and helmets. Home team is finishing infield, visiting team is warming up on the sidelines. At 4:25pm have the pregame conference, we finish and it is now 4:30pm the scheduled start of the game.

The visiting team coach comes up to me and says hey, I haven't had a chance to take infield or have my team warm up.

My question is what would you say to the coach to resolve this? And does it matter at all if the Home coach doesn't have a problem with delaying the start to have the visiting team take infield practice? Does that even matter?

Looking for anyone's thoughts on this situation.
