We've all seen them and at times we may have been one A KAREN! You know who that is.... a difficult person, that's describing it politely. Karen's make scenes and do all that is necessary to get anything and everything their way. Working in any form of a service job, Karens are your worst nightmare.
Dealing with arrogant people is never pleasant, but it can be especially infuriating when you're working a customer service job where you aren't allowed to tell the person off. Coming up with creative ways to handle the situation while not technically being rude can be an especially satisfying way to deal with them.
