At the grocery store several months ago, I saw a bunch of packages of lamb loin chops mismarked as “Cornish hen,” making them about half the price (about $4 per package instead of $8). I’m on a budget, and really wasn’t sure what to do. Tell the clerk? Buy only the packages with the proper price? Or load up on “Cornish hens?”

Then, a number of weeks later, I noticed the lamb loin chops were AGAIN mismarked — this time as “lamb shoulder chops” — once again reducing the price by almost half. IF, and this is only IF, you bought a bunch of “Cornish hens” the first time (and felt a pang of guilt about it) are you now ethically obligated to change your behavior the second time around?
