In 1981, Coles Restaurants were offering for $1.25 a Superpie and hot chips

According to the RBA Inflation Calculator, the offer would be equivalent to a person spending about $6.17 today. Fantastic offer.

For soft drinks, there was a special offer during the school holiday period: refills cost just 30 cents. It would be equivalent to spending $1.48 today, which, depending on your view, may be a good value for money or not worth it. Typically, if you want another drink at a fast food outlet or a fast casual restaurant, you would pay full price, e.g. a large drink at McDonald's costs $6.00
