Words of encouragement for the attractions hostess

Observed a hostile interaction, while in line at Disney California Adventure, between a mother and an attractions hostess. The mother was unhappy with safety precautions that were taken, to ensure her son met height requirements, and she spoke loudly and harshly toward the young hostess - the interaction could be heard from a distance.

Unsure how to best help, I wrote a quick note of encouragement, and affirmed the young lady's worth and diligence when the line wrapped around to her station. The small gesture was met with tears, and upon boarding the attraction a token of thanks: a front-of-the-line pass.
