Today I went to Nissan woodmead when I got at the boom gate I was expecting the security guy to do the normal duties like they always do "Ernest" iam not sure if I girl the name correctly I parked as usual sign and do the temperature I was in my correct lane going in through the boom gate on my left side the was a van Ernest opened for me and the other car that was suppose to be behind me meaning he let the van on the wrong lane facing on coming cars when went in I was not aware that he had opened for the car when I took off I couldn't move forward because the was a car that had parked in from of me I swerved to the left knowing iam the only 1 but to my surprise he had open for another car on the wrong lane to go in I almost knocked the car because I accelerated a d the guy did the same when I asked the security guy why he opens for another car while he opened for me as well before I could finish asking the guy started swearing at me
