Trading hours at Spar

I went to Buffalo Flats Spar at 19h40 on Wednesday and I found the store closed and they were only opening for the customers that are inside. Today around 19h45 I was at the door and they were closed already.

The sign at the door with trading hours says they are closing at 20h00. I am not happy with this because I know there are few customers late, and it makes the shopping very easy.

I am not happy at all.
