Large shops and supermarkets have a large icon of a camera with a red sign over it 🚫, capturing pictures not allowed, even when the shop's CCTV camera is obviously capturing customers. Security personnel at the supermarkets are always watching out, ready to confiscate any phone that blinks in the mall. They are always quick to run to the delete all option to empty your gallery. No use of phones at police checkpoints, in the police station and at banks. Everyone is a suspect until proven innocent. Asking for permission will make it even worse.
