Stinking attitude.

I went to a Mr Price Sport in Eastgate last night with my kids. As per the operating hours on the door and by the mall management, the store closes at 18:00. We arrived at the store doors at 17:56 to find the store closed, with a female patron standing by the door, inside the store. My daughter asked to open for her and refused, indicating that they are closed. We stood outside the door hoping that they would open for us. A few seconds later, two white ladies came by and did the same, asked them to open, indicating that it's not yet 18:00. The lady then opened the door for the ladies. As a result, I also forced my way in.

What type of nonsense is this? What does the store close before the stated operating time. I came rushing to make it before closing time as I needed one item for my daughter for a sporting activity for the next day. Why does it take a person of a different race for the staff to open the door. Is my money not good enough for Mr Price Sport?
