Im guessing you don't have daughters? When a girl gets in a group, they're pretty stupid. You'll see the kindest most polite girl turn into some kind of beast when even one or especially two or more girls accompany. Plus, when my daughter was about five, she found the word "Gucci" hilarious and would repeat it over and over and say "Gucci shoes", "Gucci bag" just to say the word . I don't think iiwoukd have confronted them or the adult, why bother, and it may give them some sort of validation or ego boost and even the adult may have issues and defended them. We live in Dubai so basically only notice if somebody isn't wearing a brand and my girls knew them before eleven .but please don't be too upset, it's just immature .
