William Hoback, of Sanford, Florida, was talking to the person at the checkout counter at a local Cracker Barrel restaurant when his gun slipped out of his holster. When the gun hit the floor it discharged. The bullet hit a kettle and sent fragments flying in several directions.
Three people were hit by the shrapnel, including the restaurant manager, Hoback's finance, and a customer who was eating breakfast.
The customer told police he heard a loud bang and then felt a sharp burning pain in his left shin. He was taken to the hospital for treatment.
Police did not charge Hoback in the incident and would not say if Hoback had a permit to carry the gun.
