Foodpump, I don't understand your comparison.
To give samples or not give them is a marketing decision you make based on its effect on your business. If you don't think it's a good strategy, that's fine. But what has it to do with KFC's decision?
What KFC is trying to do is project the (maybe subliminal) message that among fast food joints theirs is so much better than the others that employees at the other place eat KFC rather than their own food.
In other words, within the context of fast food, it's the place where other chefs eat.
As I said before, the principal is exactly the same, whether you're talking about two bucks for a chicken sandwich or $40 for an entree.
The KFC thingee really makes me scratch my head: Offer a free meal to competitor's employees if they show up in uniform. In other words, the people only come if there's free food, hence the offer. No subliminal message of superior food, only images of trained monkeys responding to food. Would they come in uniform if KFC offered 50% off, or a free toy? I dunno.... It just seems to me that KFC is figuratively "mooning" it's competitors by making it's employees show up in uniform for a free lunch. No connotations or subliminal messages of better products, service, or value. Sure it makes every one laugh, but does it sell chicken?
Then again, I've pretty much isolated myself from TV, and when I do watch (which is very rare), I always "mute" the commercials anyway. Same for radio. Maybe I'm just living under a rock.
Yeah yeah, samples. It is a fact of doing business, and I have to do it as well. The only ones who aren't giving out free samples are the banks and the undertakers......
