My family & I have been to this restaurant many time as a family member has been in hospital on & off over the past years.
In the last couple of months we have been given some discount vouchers, which we greatly appreciated, but tonight we went for a meal in the not so busy restaurant to find we could not use our vouchers at the same table, my parents were told after we had paid for our meals that we would have to move to a table on the other side of the room, again the restaurant was not full but we had to side on opposite sides.
We have been there many times before with no issues, but can not understand the reasoning behind this.

We will never go to this place again as a result, I thought common sense would prevail here.
