Of course YES you would receive a parking ticket also you would receive a ticket for facing the wrong way in a one way street.Don't forget the police would get involved and the one way street offence would carry points on her licence and £60 fine .I have seen someone reverse up a one way street so as to park his car ,not only did he get fined for the driving offence he was also uninsured,car was towed and crushed..It is sometimes ok to try to get away with stuff but if the men with their flashing blue lights see you big problems could follow .
