Well everyone has their own style. Personally I still feel strange charging something less than 5 dollars, even though society is slowly heading to a fairly cash-free economy, and these new "blink" chips in many cards make it even easier to charge everything.
I just feel a duty that I should try to circulate as many of these coins as I can and that I'm using the program to augement my FF account, not trying to milk this program for everything I can.
