The Result
Karl was able to use his power as an officer to rectify the situation and make sure the restaurant faced consequences for discriminating against a customer. The fact of the matter, this kind of behavior will not go away quickly, so it’s important to show that there are consequences.
In the End
At the end of the day, everyone who witnessed what had happened to Karl that day in the restaurant had stayed silent. Nobody tried to help him and nobody tried to rectify the situation. It was only after it was known that he was a police officer that any apology was made.
