Racial inequality

I ordered a sit in meal at Pedro's chicken emmarentia(141c barry hertzog avenue randburg 2195) the cashier made it a take away without my knowledge,after sitting for more than 10mins i looked at my slip and noticed it was a take away,i confronted the cashier who told me they don't do sit ins because there's no waiter and offered me my food in a take away box as i was sitting and eating from a take away box a white family arrived and they had a sit in next to me,the same lady who said there's no sit in was serving them with plates and full cutlery even smiling,mind you the whole staff is black and i am also black so its not a race thing it's just black people looking down on other black people because they know we never complain we just take it in,well enough is enough.the manager is Zimbabwean and so are half the staff.
