Credit Cards

Have you ever seen anybody in real life have their credit card cut in half upon rejection like they do on tv? What the fuck is this for? Does the cutter feel like they're doing their part to save the world - is there a corresponding superhero?

And what if it turns out their card is fine, but your machine is the thing that's fucked up? Wouldn't you feel like an ass? Oh, no, your machine HAS to be 10000% accurate, there's NO WAY there could be a mistake on your end - seems like a good time to embarrass the dude in front of everybody and cut his card in half!! Congratulations, total fuckwad!!

And what does this even solve - if the card is rejected by your machine, do you really think he's gonna get one over next door at the Bed, Bath and Beyonce store? What the fuck do you even care?

Grrr. Has anyone actually seen this happen?
