They should do this to everyone that begins there order with the word gimme. I don't work at a fast food place, but I see this all the time and it really ticks me off.

Indefinite detention

If I was the cop on the scene I would have ordered her to leave since that's what the business asked her to do.

But that's probably what the cop did. She refused. At that point she is trespassing. The police have to deal with belligerent people who think they are above the law and the rules of private business. It's not the cop's fault they were called in to deal with a trespasser who is illegally parked and interrupting business.

I'm not saying I would have tazed her, but at some point she made it clear that the only way she was going to leave was by force.

I just listened to that ABBA song and my body convulsed like I was being tazed.

Bitch had it coming, justice has been served, no one is above anyone in a fast food line, in AMERICA.

No one cuts in line!

Well, at least not in McDonalds..

The other version I read was that she always cut in line and they just have had enough of it that day and gave her free tazes.

Misleading story, she was tazed because she resisted the police once they were called to assit, which police will do now a days. Why would you cut a line and expect the people you cut to be ok with it?
Someone in line will get pissed and confront you, followed by the property managers calling the local authorities to deal with the argument that is disrupting business.
Once the cops get there they locate the aggressor and isolate them. If the aggressor resists, then f'em up, drag them off, tow their vehicle, slap them with a fine, make an incident report, case closed.
If there is any justice in this world then this woman got what she deserved, i hate unruly people that disturbs the general peace. AND I ESPECIALLY HATE PEOPLE THAT CUT ME IN LINE!

McDonalds. Serious Business.
