I guess the results are sound if the same criteria and data collection (etc,etc) is used each year. Saying it costs 35c is very misleading, especially when you do not clarify your accounting methods, and assumptions, let alone the parameters. Just simple marketing to drive home a point. Interesting point about the single shots. I find many establishments serve flat whites and lattes in small cups/glasses (probably less than 200ml) and only use a single shot. The same may apply for a cappuccino, but I notice they will use a double in most cases, especially when the customer asks for a strong one. What I find to be a rip off is when I ask for a double ristretto and get charged extra. Say $3, plus anywhere from 50c to $1 for an extra shot. I watch them make it. I then go back and ask for a ristretto, pay $3 and get served the exact same thing. I suppose transparency and standards vary too much, especially when the person taking orders has no idea what the barista does, or has a lack of knowledge. I believe the Gold coast easily wins a gold medal in the single shot rubbish arena.
