Jamaica Blue Cranbourne

I ordered a bowl of potato and leek soup. It came half full with one piece of nearly the end of the bread roll with it. I asked the waitress if it was correct that i only got 1/2 a bowl rather than at 3/4 of a bowl or a full bowl.
She went and spoke to someone, the chef i presume in the cooking area, and came back and said it was correct. At the end of my meal another waitress, who i am assuming was the head, asked me how my meal was. I informed her of the 1/2 a bowl and wouldn't be returning. She asked if she could do something for me. I asked what could she do? She said if i had mentioned about the size earlier....i told her i did. An apology was all i got for a $10.90 soup and it wasn't even a good soup was the rub.
