Being chased away by a Shop owner for NO reason!

I was rudely and for no reason shouted at and asked to "Get out of the way" by the Owner; Indian Female driving a Black Mercedes S Class; whilst I was waiting in a single lane driveway waiting for another customer to come out of a parking bay right outside the shop. After explaining to her that I was waiting for a car to leave so that I can park correctly she insisted I get out the way and park on the road so that she can park her car in a spot that was already reserved for Her car. When I went into the store there was a gentleman behind the counter that confirmed that she was the owner when I asked but soon after explaining what happend, He just smiled and walked to the back office. Worst customer experience EVER seeing that I deal with customers on a daily basis. And my honest opinion is that I would rather visit the licensing offices or home affairs than go back to that Shop/take away.
