You are both correct

When we speak about ROI on this forum, we are talking about average return on investment for each SNG we play. Another way to speak about ROI could be as a return on an investment over time. Since your friend made no investment, then in a sense his ROI is infinite.

In that sense, most winners get a much greater than 20% return on investment, but this is kind of meaningless to speak about, and can be debated as to the monetary value of our time, energy, etc...

So you are right in the sense that we all talk about here, and your friend is right in a smarty-pants kind of way that doesn't really matter much anyways.
