Discounts at airport food outlets!
Yes, indeed!
I rocked up to the coffee bar in the departures lounge at Cairns on Monday and ordered a cappuccino in a mug. "That'll be $5:30", she says! Then she spied the ASIC dangling from my pocket, "Oh sorry! That's $3.80".
I only have to drink another 119 mugs of coffee and I will have recovered the cost of my ASIC!
