Each team that has concession duty at Kenny Askew park is required to provide 6 people to work in the concession stand at a time. You can set this up in shifts with your parents as long as at any given time during your duty you have 6 parents in the concession stand. That means that if you have 12 volunteers, 6 of them can work part of the shift and the other 6 can work the other part of the shift.
