Bad taste in one's mouth

I had the distasteful pleasure of trying to eat at this restaurant at the Galleria Mall about 2 weeks my wife and I drove about 20kms to eat at this restaurant which had a special which we didn't know ended at 2pm my wife started to order the meal at 13:58 only to be told that she couldnt because the special ended at 14:00 last time I checked she was order before the special could close also I tried to speak to a gentleman who I assumed was the manager and showed him my watch that it was before 14:00 I even said I could have been a mystery shopper to which he said to me it doesn't matter what you are shocking we speak of black lives matter all the time I am of Indian origin and he is of black origin how would this have faired if the roles were reversed I wrote to the customer care line of this restaurant and 2 weeks later no resolution
