What action can potentially result in receiving the most demerits according to the established rules?

Allowing a non-team member to sit with the team can result in receiving the most demerits because it directly jeopardizes team integrity and discipline. This action undermines the cohesion and focus vital for a drill team, as it introduces distractions and disrupts the team dynamic. Teams often emphasize accountability and exclusivity to maintain trust and synergy among members, and permitting outsiders can break this essential bond.

While the other actions—improper bus conduct, talking while performing, and unsportsmanlike conduct—are all serious and can certainly lead to demerits, having a non-team member present during designated team activities or events raises significant concerns about commitment and unity. That is why it typically carries heavier consequences compared to other infractions.
