I used to work at blockbuster, and about two years ago this happened, and I figured I'd share and tell you all that occasionally awesome things happen.
Anywho, I'm running some returns, and there are 2 siblings in the store, one is a 15 year old girl and her younger brother, probably 11 or 12.
I catch the brother trying to stick a video game manual into his shorts and I just stare at him with murder eyes till he puts it back, and I go about my return running, mulling over how to exact delicious justice. The girl comes up with a rental, so I go behind the counter and help her.
After I tell her when her movie was due back I said "Oh, and tell your brother the next time he tries to steal video game manuals, I'm not renting to him anymore."
She looks shocked, gathers him up, and walks out of the store. I worked in a pretty affluent area so it's not like this kid needed to steal.
About five minutes later, the brother is being dragged into the store by the arm by his mother. She comes up to me and asks if he really attempted to steal, to which I reply, "Yes, it was the manual for a wii baseball game."
The woman starts hollering at her son, grounds him for a month on the spot, apologizes profusely to me, smacks him upside the head, and walks out, all the while berating him.
Felt good, man.
