Bad Attitude

I had entered the Pep store 5 minutes before closing time, to buy airtime. The lady at counter started shouting that they are not paid overtime and I was there to shop lift. I've never shoplifted in my entire life, I felt the accusations were embarrasing and tried to talk to the manager but he was no use. The lady continued shouting at me while the other staff members were taking video of her confrontation. This is the attitude I've always witnessed in this Pep store but I has never been directed towards me. I guess these employees are taught to treat black customers with utmost disrepect!!!!!!
