A woman missed out on her fast-food order in Mornington overnight after being caught allegedly three times over the alcohol limit.
Police responded to reports of a woman driving erratically at a drive-thru on Nepean Highway about 11.45pm on 26 April.
Officers approached the vehicle and gave the 56-year-old driver a preliminary breath test which returned a positive result.
She was conveyed to a police station for an evidentiary breath test, where she allegedly returned a reading of .149.
The Somerville woman did not get what she ordered and will be charged on summons with driving offences.
