They’re Very Very Cold

(At my job we keep a large rack of hot sauces for our customers to use for their food, with the bottles marked with a number 1 through 10 on a scale of how hot they are. While organizing and restocking them my coworkers have the following exchange:)

Coworker #1: “Hey. So, how do they figure out how to number how hot these are?”

Coworker #2: “I think they take someone’s temperature before having the hot sauce, then take it again after.”
