Getting screamed at

So here's what happens. Engen garage bedfordview is filming a new advert for television. I was not aware of this at the time. Me walking into the shops gets yelled at from across the the station to "walk faster and not make it obvious stupid" where the exact words. I find this very intuitive aswell as abusive. I feel the way I was treated is not customer service at all and don't appreciate to be spoken to like that.
