4 hours, at a mall.
nope. if I need something, I walk with a purposeful stride to the nearest shop containing it, find it, check if the price is acceptable, buy it and walk out with a purposeful stride.
What the heck would I be doing for 4 hours at a mall...? Well, I'm a guy and I don't window-shop (ever), I never understood why someone would go to a shop without the intent of bying anything or not knowing what they are going to buy before entering and I got better things to do than just loiter around searching for eye-candy.
I don't spend 4 hour at a mall, ever. Not even when I'm christmas shopping.
