When that literal scenario happened to me the first time, it was for a whopper meal and a movie, back when combined it came to about $10 and I was about 17. So, 34 years ago.

None of this transactional thinking is exactly new. What is new, or recently added on to this behavior is the mantrums when they get denied and the increased levels of general aggression as well as strategic coercion and manipulation. I think it's safe to say there's also the more widespread acceptance that this behavior is both normal, natural, and acceptable.
