@antkm1 I remember the gargantuan Best Buy opening in Xu Jia Hui district of Shanghai in 2008/9ish. Advertised as their single largest store in the world. Yet it seemed to me to be mostly wide aisles and very few products. It didn't help I could buy anything there 30% or more cheaper across the street at any electronics mall. But back to floor room, no doubt, when it is busy in China, you need aisle room.
