On a recent trip to Maggie we noticed a trend of some concern. When shopping at cafés etc we noticed on several occasions were were short changed on purchases. For example, for a $4.50 cup of coffee we received just 30 cents change from a $5 note. I know it is not much but it happened 3 times in a week and if someone does it 20 times a day that earns the person $8 a day. It was mainly travellers from OS that we're doing it but if it doesn't stop it will become a major issue. Magnet Island is quite expensive for food, groceries etc, so it is yet, another cost issue to consider. Has anyone else noticed this?
