Is anyone else familiar with this expression or know of its origins ? It's something that's been used in my family at least for decades to describe an unusually busy place or situation. I believe it's a popular expression in Merseyside but I honestly don't know where I heard that. Also, given the disapproval that accompanies other sayings like 'having a paddy' or 'paddywagon', would Paddy's Bazaar be considered offensive these days ?
