When I saw this I had the same thought. The front line staff doesn't deserve that sort of staged badgering, they are working within a very defined scope and those types of encounters only frustrate them and ruin their day.
Instead, send these expressions of dissatisfaction to the audience most in a position to act and respond. Email corporate, maybe buy a single share of Disney stock and email investor relations

It might seem like a drop in the bucket, but if half of the well written and thought out responses I've seen on the DIS were sent thru the proper venues at Disney, it would most definitely make an impact.
But not some poor front-line CM trying to be helpful. Seriously not cool.
