Bad customers are a common phenomenon in the business world and can be a major source of frustration for businesses. These customers can range from those who are overly demanding, rude, dishonest, or simply difficult to please. No matter the type, dealing with bad customers can be a challenge for any business. One of the most common types of bad customers is the "angry customer." These customers are often unhappy with the product or service they received and take out their frustration on the business's employees. They can be rude, disrespectful, and sometimes even verbally abusive.
