that's fair. to your point i think i have become more fiscally conservative since college, but i don't think i've gotten that much more. nab's going to be pissed at me for saying this, and i'm going to have to step out of character for a minute, but $20-$30 is basically pocket change. getting frustrated over seeing someone else waste such a small amount of money is silly, unless you're so far to the left that you think any money not donated is a shame or anything used for yourself is a waste. i've gotten haircuts that were more expensive than that. now, we start talking like $200-300 THEN i would say "ok yeah that's stupid" but lets not be pedantic over an amount that's essentially a rounding error in the grand scheme of things.
and now i'll shut my conservative side off and go back, back to the past, samurai jack WHACHA.
