Re the time violation thing I think they need to have a bigger allowance ( 30 seconds would seem fine to me ) but then actually enforce it far more strictly than the huge latitude ( and frankly often dereliction of duty ) given these days ( and then not unnaturally some feel picked upon by an umpire seemingly deciding today's an enforcement day ). I believe it's currently 20 or 25 seconds depending on tournaments.

As mentioned above more latitude has to be given in non ball kids ( or indeed few ball kids ) occasions and common sense says take out reasonable ball retrieval time.
