Rude security guard

I was coming to the mall as I usually do. I used the back entrance by cross street and I was walking into the premises, the security is incredibly rude ...shouting at me to walk on the other side despite countless others walking on the side that I was walking on. He was clearly using his job as an excuse to get in my face which I feel is highly inappropriate. He is a skinny guy who was wearing a blue buff for a mask.
