Never say ‘I’m friends with the owner.’ Restaurant owners don’t have friends. This marks you as a clueless poseur the moment you walk in the door.
I need to tell everyone who complains at the restaurant I work at this exact statement. They are all “friends of Dave,” and they all will get us fired because they “know Dave” if we don’t do what they say. Dave only cares if they live or die because if they die he loses a revenue stream.
