Wow... lots of good arguments on both sides.
We've got a couple of radio stations in town that have been known to give out thousands of dollars at a time, simply for listening. It always seems to happen at ratings time, when they want to be able to increase their advertising fees.
The people pay nothing... they don't even need to plug the station after winning... and they get the money. I'm sure that my middle-sized midwestern town isn't the only one that does this on a regular basis.
The radio station's actions after the contest seem, IMHO, to condemn them more than anything else. If they have done nothing wrong, why send the woman home rather than face up to their tomfoolery? And why offer $5000 in cash to settle if they truly feel they have done nothing worse than set a listener up for a joke?
If it walks like a duck and talks like a duck....
