When I worked for *big department store* we had a regular customer who would come in, make the minimum payment on her store credit card, and immediately buy more shoes (probably other stuff as well, but I worked in the shoe dept.). She handed me a copy of her statement one day, as she didn't have her plastic card with her---she owed more than $14,000! On a store credit card! All I could think was, "Dude,*big department store* OWNS your ass."
