If one goes to the Movies at Sheepshead Bay on a Motzei Shabbos in the Winter you will see lots of young frum there (Flatbush types, not Borough park types)
Clearly they are all not doing averiahs, you will never see such a crowd at a Mcdonalds. For these people their Hashkafah allows it. I am sure their parents know where they are. (Or should know where they are)
