It’s not that unusual for family members to cut into or out of ride lines after jumping out to grab a drink or (assumedly more usual) use the bathroom, though the report is unclear about whether or not the bulk of the conflict was over the spilled drink or the line cutting. However, what is clear is the incident escalated and the two families began fighting.
