with mass production, sometimes you get defects. these things happen. one time i bought myself a box of hallowe'en candy and one out of the 100 or pieces in that box just so happened to be an empty wrapper that was fully sealed. i called the toll-free number on the box, told them that it happened not knowing what to expect, and they sent me a bunch of coupons for free chocolate as an apology for the inconvenience. no, my local newspaper didn't call me up to ask about it.
