Here's an example of fantastic customer service from a dollar store in Fort Worth, Texas:
A Family Dollar clerk in Fort Worth, Texas was charged with aggravated assault with a deadly weapon after police said he used a crowbar to club a deaf customer. Cody Goodnight, 30, has been deaf since before the age of 2 and uses sign language to communicate.
When Goodnight tried to pay for two bottles of Sprite with a $5 bill he was assaulted by the store clerk. Investigators said the clerk, 20-year-old Ricky Young told them he thought Goodnight was being rude by not talking to him and hit him in the head with a crowbar.
