Sworn at by Maders Butchery

I had the most unfortunate incident today as I was leaving Maders Mayville Butchery.I was sworn as I was leaving the gate .I do not understand why I was subjected to insults .There were two white males and one swore at me.I had to reverse back and got out of the car to try and and confirm if I had heard correctly.The one who was insulting me was ordered into his car by the 2nd one who opened the gate for him to leave after which he told me that I was wasting my time asking him about the incident because he was on the phone and the one who insulted me dies not work for them but runs his business in their premises.

I am still confused as to what I did to deserve the insults and humiliation , unfortunately I was with a 10 year old child who heard all the insults . I asked the gentleman what gives them the privilege to swear at a customer.I certainly hope that it's not race related .
