On 2 separate occasions the invoice provided to me by the Excelsior Jones (Queen St, Ashfield NSW) cashier did not contain an ABN (Aust Business Number). I need this in order to make a reimbursement claim at work. When I called up and politely asked for this, I was told to call back and speak to the 'manager'. When I did speak to the 'manager' several hours later, he flatly refused to provide an ABN because it is 'private'.
