Answer:
I would go up to the coach, and have a talk with him. "Kids or anybody/people need water and we could get dizzy and Etc if we don't get water." something like I would say, other than that I would just yell at him. But again PEOPLE NEEEEEEEED WATER PERIODT.
Explanation:
I don't really have an explanation for this one but people need water so anything that is evolving needing water will help.
I hope this helps ❤
