karma, it's all about karma.
bob, your story reminds me of a recent experience i had.
i will not go into detail, lets just say...i am waiting for the good karma to return to me.
p.s.
sure bank machines have cameras, but if you were not robbed, or someone did not break into your account, by coersing/threatening you, they (the bank) wont resort to digging through camera footage to return your money. unfortunately, if you left your money there, that is your fault and your loss.
