Ugly personality

It's also misinforming the kid as to why she got it: because she was so polite

If I get a really polite young kid at work (ice cream shop), I'll give them a chocolate and I make a point of telling them it's because they were so polite, patient, thanked their parents for getting them ice cream, etc. Good manners should always be encouraged :)

People simply don't expect kindness anymore

That woman was a bitch in the end
