Over the weekend, a KFC employee in Johnson City, Tennessee posted a photo on Facebook of herself at work . . . LICKING the top of a large tray of mashed potatoes.

KFC says that those potatoes were never served to customers.

The employee was fired, and KFC's corporate office says they sent a quality assurance team to the location to, quote, "reinforce and retrain [employees] on KFC's high operating standards." 

Have you worked in the food service industry?  What would people freak out about if they knew?
