First off, I've been behind stupid soccer moms who decide in mid transaction that they've left their cc in their mini van and had to go out to get it, while a line is forming behind me that slowly snakes through the store(since as we know BB rarely keeps more than maybe 2 registers open at a shot).
Then, Miss Self Important Soccer Mom comes back in, yammering loudly on her cell phone while fumbling through her oversized faux Gucci purse she just had to have to keep up with the other soccer mom bitches.
So, instead of actually saving US some time waiting for her too important ass to find her cc and get off the

in cell phone long enough to acknowledge the clerk if the cc she tries doesn't work, she yammers on.
What does this have to do with the story at hand? Little to nothing, except for the fact that Ms. Important there took the cell phone call, leaving her cc and the cd player behind because she figured the world would stop and let her come back in on HER schedule to finish her transaction and be on her merry self important way.
Take the credit card and her probably omnipresent cell phone, shove both of em up her ass and skip the taser. Oh and give her a swift kick back outta the BB store.
I've nearly been sideswiped by about 30 assholes on cell phones too busy to realize they just blew through a stop sign but super involved in their conversation. Outside of REAL emergencies, cell phones have NO

IN USE. If you can't pay attention to what's going on around you while using you, it should be either 'use cell phone' OR 'drive', not BOTH.
As far as the story goes, she shoulda taken her cc outside with her and come back in to finish the transaction by grabbing another cd player. The cop WAS in the wrong for using the taser though, since a firm bitchslap woulda worked SOOOOO much better and I probably woulda cheered if I were there.
