Don't get me wrong, I love coffee. The reason why I don't buy coffee with your $$ is because, when it comes to coffee, I am already set. Every month, RwandaBean Coffee delivers 1 bag of freshly roasted coffee to my door. So yeah, I don't really need coffee, RwandaBean Coffee got me squared away.
But, if you want to let me use the "coffee" $$ you support me with however I set fit, you can still "buy me a coffee" and you can see how I will use your "coffee" $$ for non-coffee expenses.
