Could work. The price of a pint or a glass of wine at the bar is actually one of my current "what's that worth" metrics. I know that my wife does the same thing, "That's nothing, just a glass of wine I could do without," etc. In reality, of course we still end up buying that drink.
When I was in my late teens, everything was judged in terms of CDs - $100 was three and a bit CDs, for example; in Australia, a new CD at the time was about $30. The first paying job I had on the web, I remember instantly thinking "Wow, x CDs per week; this is going to be great!"
Now it's either drinks while out or international flights.
