When one video store employee realized that a customer was coming in just to creepily watch an early Harry Potter movie, she quickly took matters into her own hands and had him removed by security. The next day, the man was back for similar reasons, and once again security did their job. This time, the man was banned for good, and his photo was distributed around the store's mall. Unfortunately, that didn't stop him from continuing to try and enter. 

Anyone who has worked in retail will tell you that annoying customers are more common, and more troublesome than your wildest dreams. Unfortunately, they have no choice but to bear down and take the harassment. These -- workers decided to share their stories of customers from Hell, and from Black Friday to random Tuesdays, there are plenty Scrooge-like shoppers to choose from.
