When the clerk followed him outside the man allegedly pulled a gun, which the clerk was able to grab. The suspect then went back inside and tried to pay with a debit card, which was also denied.
WTF?!
Lincoln had a convenience store hold up, a few months ago, while a uniformed police officer was standing inside. Guy was charged with a string of these hold ups. Pretty dumb not to look around to see who is inside the store.
