A jury rejected the defense offered by 26-year-old Gregory David Moore Jr. The Uniontown man said he didn't realize what he was doing because he had consumed a spiked drink at a party.
Moore went to the store after the party and was pre-paying for some gasoline when he undressed and told the female clerk, "I want everything."
Police say the incident was recorded by surveillance cameras.
Moore was convicted Thursday. His sentencing is scheduled next month.
