Extremely rude and unprofessional staff member

I visited The Marco Polo at around 11 AM on 04/02/2022. This was my first time visting and I couldn't believe how rude and unprofessional the lady at the security counter was. All I did was shield her view with my hand on the screen while typing in my ID number and she laughed loudly in a mocking tone in my face. I will never be back, I've never been treated with such indignity and disrespect by anyone like that before.
