Getting fed up

I just left yet another Kroger that treated me like a common criminal for using coupons. I'm getting so fed up with this! They adjust down coupons when they know full well they're getting the full value back from the manufacturer. Way to profit off the manufacturer. Isn't that fraud? Apparently giving me the discount that's legally allowed to me is. And on top of that, they kept insisting my internet printable were copied. Seriously? They're from Smart Source, not Coupons.com. Different systems equal different verification methods! I'm just tempted to scrap coupons and get food stamps. Those people are held in high regard, not us looking for legitimate ways to save!
