For instance: Time Warner Cable screwed up my cable package, charging me 220$ (a la carte) rather than 90$ (bundle). I contacted them, they admitted the mistake, and fixed the next month---I still ended up out 65$. I'd really like that money (moral imperative), but there's no legal way for me to seek relief for that small amount. If TWC messes up 1/50 accounts, once a year, for 50$, then they stand to make 500k--1mm$ a year just in my area. There's literally profit to be had between the legal cracks.
