Extremely disappointing experience at Hussar Grill

We went for Sunday lunch yesterday at Hussar Grill Willowbridge for my mother's birthday. We were 9 people. We had an unfortunate incident where we found a big piece of glass in the sweet potato snacks they put on our table. We called a waitress and showed her, who then went to call a man I assumed was the manager. His attitude was shocking. He acted like we were bothering him with our complaint. He blamed some or other waiter for probably dropping the glass in the bowl. He was not sincere at all and did not even offer to compensate us. When my father jokingly said he has a couple of options for compensation, the manager said that sounds like a loosing deal for him. He then left. They did not bring us a new bowl of sweet potato and he NEVER came back to our table to check on us. He avoided us for the rest of our meal. The food was good as always, but I really hope he is not the manager as he is not customer orientated at all. We expected an apology and all we got was a lousy excuse that it must have been a waiter. For a restaurant with such a good name, this was appalling. This person should NOT be working with customers!
