Everybody is discounting the approach of SERVE her, AND call the cops. That isn't much of a reward for her in the end.
She didn’t get zapped for cutting in line. She got zapped for refusing to comply with LEO.
If they’d have already served her and she left, LEO would have no reason to stop her, would they?
Sorry to rain on your parade here bud but please pray tell just what are the cops going to do to this whiny spoiled little beetch if they even bother to go looking for her upon following your advice? Pray tell again what crime did she commit to warrant a man hunt for her afterwords? No the McD' employees did the right thing and I applaud them and the responding officers actions. At least she was creating a public disturbance at the drive thru.
