That's crazy - I guess she had something to hide? Never heard of the revolving doors 'locking down' before. Interesting that the police were there so quick too! Was it an upmarket store?
They use a lot of EAS in Chicago. If you live here, sooner or later a tag won't be removed or desensitized and you'll set the EAS alarm off as you are exiting a store. A normal person just hands the bag to the clerk and they find the item causing the alarm and you are on your way. She wasn't acting like a normal person does. She was freaking out.
It's not really an upscale store, more middle of the road. They have grocery's on one floor and nice clothes and kitchen accessories on the other floor.
This morning on French TV I saw a new Nokia 925 commercial titled, "See In The Dark", showing pictures taken at night and under extremely low light conditions.
I am not sure. I have seen more Windows Phones on this trip, but people will have cases on their phone so it's hard to tell. The tiles are easy to spot.
