We allow our kids to order a meal from the concession stand through Google Forms for home games. All meals must be paid for by 530 on gameday. Then, at the beginning of the 3rd quarter, my section leaders go and pick up their sections orders in boxes with lists of what was ordered. We eat but are ready to play if we score, etc.
For away games we do the same and the kids pick it up as we enter from the field. OR we eat pregame and have a snack during the 3rd.
Might not work for everyone but it works for us.
