"Happy": They wired this thing up with, like, five thousand volts. What kind of bank does that?hit back with means outside of the law. Realization is typically an "Oh Crap!!" moment. Depending on the types of ties the victim has, the crooks might get a warning that they've made a fatal mistake. Other times they won't find out until the first drive-by on their mother's house.

In that trope, the mugger is typically a mook and the monster is a main character, while in this trope, the robber is typically a main character and the victim is a villain. For cases where characters are deliberately robbing criminals because they think they deserve it, see Just Like Robin Hood or Karmic Thief.

On realising this, the crew curiously doesn't panic, but instead calmly approach the banker with what they feel is a reasonable deal — having not known the bonds belonged to him, they offer to sell his bonds back to him at a generous price which will, on top of the insurance he'll receive for them anyway, will see him lose out less than he would have had they sold them to a third party. Unfortunately for them, the banker isn't in the mood to be reasonable and so orders a hit out on them. Interestingly, the hit backfires and Neil, himself now no longer in the mood to be reasonable, promises the banker he's pretty much going to die painfully. The banker is consequently the one who spends most of the movie fretting for his life — until he gets hooked up with Waingro, an Ax-Crazy lunatic with a grudge against Neil, at which point things go From Bad to Worse for pretty much everyone concerned.
