No respect for clients

Hello!
I was a loyal customer of this restaurant until that day. Once, 6 of my friends decided to have a Birthday dinner at home. Instead of going to sushi, we ordered it. The order cost more than 100$. Upon delivery, the sushi was a mess! I cannot say that before the customer service at this restaurant was good (rather very poor, as you constantly getting a feeling that you are a nuisance there and waiters were serving without any enthusiasm, if you know what I mean  ), but my husband and I were often dinning there (almost every week) as it is very close to our house. As said before, the order was a mess. Half of the rolls were falling apart; some were even damaged (I think is it due to the not careful handling of food and poor preparation of the order). So, as you all guessed, the celebration was ruined… Usually, I am not a complainer, but this incident got me very mad! So I have called them. After explaining the situation to one of the waiters, she told me that the BOSS of the restaurant himself was delivering the food and then it MUST be OK. I was shocked! I think she knew who I was, as I said that we were loyal customers and never received the food in this state. She said that the only thing they can do for me was to give us 10% discount for our next order…not to replace the damaged food as all respected restaurants would do, not even to give a credit for the next order, but to give 10% discount as I would normally get if I take the food out. After such disrespect, I told them that I would never visit this restaurant again. So this is my story. This is how the management (correction: the BOSS) treats his loyal customers. You decide: do you want to dine in the good restaurant with a nice service where you will be respected, or in a diner (which is more similar to fast food place), where nobody cares about their customers and service.
