For all reasons stated above, I agree in calling, but I can see where someone could be happy with folding and wanted to play devil's advocate a bit. This may be elaborating a bit on 'scared money.'

This is in a casino, and OP didn't mention the actual buy-in, only that he had $200 behind. Online the buy ins are pretty standard, but my nearest casino's NL game is 2 $5 blinds w/ a max buyin of $200. So it could be fair to assume OP is up in his session.

Online players are spoiled in the number of hands we see and the unlimited hours we can play. In a casino, where a tighter player may only be playing 4 or 5 hands an hour, one hand like this will make or break your whole session. It could be a long time before you get another chance to make that money up.

On the other hand, the majority of live players at this level are horrid, so the chances of getting payed off/doubling up when you do hit a monster are very high.

If OP chooses to toss a flip even when getting odds because he wants to finish up on his session or wants to keep more money behind to exploit bigger edges later on, then I can see where he's coming from. However, he needs to be honest with himself and admit he made a mathematically incorrect decision because of these reasons.
