Rewrite the following passage in the passive.
My parents own the best restaurant in our town. Last weekend my father dismissed the head waiter as he had stolen some stock from the cellar. My father is going to hire a new waiter as he is doing all the work by himself at the moment. He asked me to help serve food. However, I mixed up all the orders and the customers made several complaints. I'm sure my father will never ask me to help him again.
