Michael Moir was sentenced to five months for the incident at a takeaway in Aberdeen. A furious row broke out after Moir, 23, and his girlfriend, Megan Ross, 20, discovered she had not received a portion of cheese with her chips and gravy order.
Aberdeen Sheriff Court heard Ross threw the food at worker Kathleen Hadden at Balnagask Chip Shop, and then Moir head-butted her.
Moir, whose address was given in court papers as 203 Portland Street, Aberdeen, had previously pleaded guilty to the assault and was sentenced to five months in prison. Sentence was deferred on Ross, whose address was given in court papers as 114E Victoria Road, Aberdeen, after she pleaded guilty to assault.
