A man robbed the Kroger on Hartland Parkway at gunpoint Monday night, but most shoppers who saw the man probably never knew what had happened, police said.
The crime was unusual because robbers rarely target such large stores.
"I've never seen a store that size get robbed," said Lt. Chris Van Brackel of the Lexington police department.
The man walked around inside the store, then walked up to the customer service counter. Armed with a small black handgun, the man demanded cash, Van Brackel said.

The clerk complied, and then the man "nonchalantly walked out." Police say they think the man left in a vehicle, but they do not know what kind.
Van Brackel said police hope people who were shopping at the store will see news reports and help identify the type of vehicle.
"There were people going in and out of the Kroger at the time who had no idea but have seen this guy," Van Brackel said.
The man was described as white, in his 20s, with a thin build, dark hair and glasses.
He was wearing a camouflage baseball cap, a camouflage jacket, blue jeans and work boots.
