Grocery store injustice

Maybe it's just me, but I thought grocery store aisles were like highways–traffic is supposed to flow both ways.
So why is it when I get to the store, the aisles are clogged with people all going the same direction but double parked so no one in either direction can pass?
And why is it that 60 percent of the coupons I want to use are for items not stocked by either grocery store in Williston?
And lastly if you are using food stamps, don't flaunt your $400 boots and $100 jeans as you whip out more cash than I take on vacation to pay for your toilet paper.
There's something wrong with that picture.
