Kicked out of restuarant after paying the bill

Ocean Basket (St Lucia) kicked us out by putting a "reserved" on our table while we were still sitting in the restuarant (AFTER PAYING THE BILL).I asked why this was done particularly on our table as there were still numerous vacant tables around us.I was not given an answer.So we got up and left.Im quite sure this would never be done to a lighter skinned race.DISSAPOINTED I thought we were passed that era
