Debonairs Rude Employee

I was disappointed at Scottsburgh debonairs pizza, I arrived at 8:30pm and the employee closed the door on me saying they close at 8:30pm whilst it's written 9pm at the door. I asked him why write 9pm at the door and he just slammed the door at me. I am very disappointed whist being a fan of debonairs I am definitely not going to Scottburg mall
