Fast Company | Where's the Loyalty?: "Where's the Loyalty?
Do loyalty programs truly engender customer loyalty? Or do customers keep coming back for other reasons?
If only I had a dollar for every time a cashier asked whether I had one of those loyalty cards ... and another buck for every time I answered, 'No.' Hey -- give me 50 cents more each time I'm asked if I want one of their blasted cards (no, again), and two smackers if they ask me for my ZIP code. My phone number? They couldn't afford it."
