I'm sorry to hear you had a similar experience. It's not nice to be told you're doing something wrong, when there's no way to know it's not allowed. Good thing you got away with it.

I did not want to push it as there were cameras everywhere and most likely they were watching me. However, imagine how many teenagers are taking selfies in there, just to show off on social media platforms. Anyway, I'm glad I could take these photos and learnt how to be more careful next time. Not here though.
