Burglars will learn from 26-year-old Kenneth Plummer to always check their belongings before leaving a crime scene.
He was arrested by Florida Police after stealing $600 cash from a nail salon, but unwittingly dropped and left his cellphone.
After the heist, he was seen casually having breakfast at a diner beside the salon, counting his money.
Later that day, Plummer was busted after a homeowner allegedly caught him trying to break into the home and diamond jewelry went missing.
He will count many days for his next salon visit as he heads to jail on charges of burglary and grand theft.
