If I had the pot odds, I would have likely called. You're drawing to the nut flush, and you also have straight outs as well. (Not really a lot to count, but still).
It's a tough decision, for sure. You have to figure the tight player has something - either an over pair, set, or a decent ace (maybe even AK himself). Maniac you likely put on any two - he could have flopped two pair, or could just be making a play for the pot. He could be drawing himself too, with something like AhQs.
You can't think of your chips in terms of what they can do for you (i.e., pizza). Once you buy in to a game, have the mindset that you've already spent X amount, and if it's gone, it's gone. The important thing is to play well - sometimes the luck just isn't with us.
I'd probably make the call, and be glad that at least the good player, not the maniac, won the hand.
