But that's a darn good example because free food with a lecture (or timeshare opportunity, or conference on industry tool) is a really common occurrence marketing wise and it raises a question that I can't answer in terms of legal and moral right - those lunch and learn conferences, do some people feel pressured to attend because it's subsidizing the cost of their lunch that day? How much time do they lose to engaging in such things and how many of them missed better job opportunities because of it.
