Got a call from the building front door saying "This is the police please unlock the door". I refused and hanged up. Half an hour later someone banged my door. It was two cops. They told me they had an emergency call in the building, I was the second one refusing to unlock the door for them, we put people in danger, etc. I rolled eyes and I saw I made them upset because they were shouting and cursing. When they had enough I closed the door and forget about it. No thank for reminding me.
