We've all encountered them - the customers that can drive any service worker crazy. Whether you work in retail, hospitality, or any other customer-facing role, you've likely come across customers who seem to have a knack for making your job more difficult than it needs to be. From demanding and entitled to rude and impatient, these customers can test even the most patient service worker's resolve. One type of customer that can drive service workers crazy is the 'know-it-all'. This customer is convinced that they know more than the person assisting them, and they're not shy about sharing their opinions.
