Bad customer service

We requested the waiter to change our order because the smoothie was not right. We than after requested our bill and noticed that the smoothies we had ordered where not included in the bill , the sad story is the ninos manager Terrence and Joudie K demanded that the waiter should for the smoothies , where else it wasn't the waiters fault that the smoothies we not right and tastes bad . I decided to confront the managers about this matter that why they making the waiter pay. The managers responded by telling us it's his table and why is the waiter telling us that he should pay the bill. Both managers decided to dismiss the waiter and requested him to leave for a hearing . The waiter was not at fault but the managers
