Oh man, my buddy lasted 15 minutes into The Room before bolting!

Calibrate the probe in boiling water first, then trust your senses over the numbers.

Three years ago I watched a guy in a Delta uniform at DFW airport tap his card on a reader that had a tiny blue light that didn't match the rest of the machine. I still yank on every pump handle and card slot like I'm testing a pull-up bar. My buddy thinks I'm paranoid until I showed him a YouTube video of a skimmer that fits so flush you need a flashlight to spot it. Now he checks the gas station pumps before we even get out of the car. Honestly it's become a weird hobby, like geocaching but with more financial dread.
