My own anecdote on this follows:
I am at the local stop-'n-rob, for reasons I don't recall. When I walk in, there is a ~ 40yo woman, (going on 20), supervising 2 girls, 1 about 10 (going on 20) and one about 12 (going on 20) who look like their on the old "Supermarket Sweep" tv show. They are piling TONS of pure junk food (chips, candy, sodas, cookies) on the checkout counter. I expect to see the mom take an active part in putting an end to this, but I realize she's directing this traffic and making suggestions. Okay, well, whatever. Near the end of this spree, the mom goes over to the coffee bar and mixes some sort of frou-frou brew, and stands in line as the clerk starts bagging this trash up. She hands over what appears to be a credit card, and points to her coffee to be added on to the 3-digit bill. He demurs, indicating that the coffee is not eligible. It was only at that point that I realize this is a food-stamp horror story, right in front of me. Anyway, she begins to berate the clerk, stating that she "does this all the time" referring to the coffee, I guess. He stands his ground, and the kids are hauling the bags out to the car (that I can't see). She huffs and puffs, and then says "Well, I'll leave the coffee on the counter, and I'll have to go to the car and get some cash". She storms out, and the next thing I here is the roaring of the engine and squealing tires. You guesssed right, but it was an older Caddie, not brand new.
My tax dollars at work, I guess.
