I entered into the building via Novotel Hotel and met eyes with a female worker who was at the reception area giving people tickets. She stared at me and yelled out loud, 'take your hat off' in a very rude condescending tone, which was very embarrassing in front of my boyfriend and his family. Correct me if I'm wrong but I was not aware that an RSL was THAT fancy to have to take your headwear off (btw I was dressed decently and wore a beret, not some sloppy hat), and that doesn't even matter, she could've just told me politely anyway. Completely unprofessional.
