** People who write a letter on PFB, and preface their letter by saying "I'm a good Christian, but...", as if somehow this gives their complaint more validity.

** People who threaten to tell ALL THEIR FRIENDS not to patronize their business. (Yeah, that'll teach 'em!)

** People who don't understand the term "At Participating Retailers" printed on their coupons, and then can't, for the life of them, understand why a certain store won't accept THEIR coupons. From there, they insist that it's personal.

** People who weaken the power of PlanetFeedback by posting bogus letters.
