I was driving at centurion mall there was 2 of these guard with cars they where parked 1 left and 1 right ( in a no parking zone) so i wanted to go through the middle of them and while I was passing the guy opened his door so I hooted or he wil hit my car. So the guy in car FG 09 BG showed me **** off what is my problem . So i got mad
