HOLLA ON THE GO: Creeper in a car

I was getting gas in St. Louis. A guy started yelling at me from inside his car. I just went inside and paid. He waited outside for me to come out and yelled at me some more. I told him no thanks and walked to my car. I got in and locked my doors. He pulled his car around to block me from leaving. He kept asking me to roll down my window and kept asking for my number. I told him no many times and finally said I have a bf hoping he’d go away. Finally I yelled and he sped away angrily.
