Of Microwaves And Microbrains, Part 2

(My coworker is getting an extra side of sauce for a customer. However, she manages to grab the only metal dressing cup we have, fills it with the sauce, and then places it in the microwave. Thankfully, I catch her before she presses the start button.)

Me: “STOP!”

Coworker: *still pressing buttons* “What?”

Me: “Stop! Don’t put that in there!”

Coworker: “What? Why?”

Me: “That’s a metal cup!”

(She opens the microwave and looks at the cup.)

Coworker: “Oh!” *laughs* “This is why I can’t use the microwave at home!”
