Yesterday morning I filled up at local Servo in Curra QLD. Displayed price on Bruce Highway entrance for E10 95 octane was 112.9 but bowser reading was 114.9. I was in hurry and didn't have time to query. On return from Brisbane same afternoon, I again filled up at same Servo and confirmed bowser price with entrance display discrepancy. When I questioned cashier he said "girl must have forgotten to change bowser to correct 112.9" (as displayed at Highway entrance). He then said he couldn't correct or refund as I'd already filled up and claimed "you're the first to notice". I have both tax invoices clearly showing times, cost per litre and register receipt numbers.
