Will Get A Roasting For That Later
(At the end of my undergrad, I started working at a small local coffee shop. I end up graduating a semester early and decide to work at the shop full time until the lease on my apartment is up. When I switch to full-time, I work with an older woman who isn’t quite up-to-date on her science. This happens right as we get a new light roast, so we offer light, medium, and dark.)
Coworker: “Hi guys, would you like to try our new light roast today?”
Customer #1: “No, thanks; I’d rather have the dark roast. More caffeine.”
Coworker: “Actually, lighter roasts have more caffeine than darker roasts!”
Customer #2: “Wait, really? Why?”
Coworker: “Because roasting the beans longer makes more caffeine evaporate out of the beans!”
Me: “Um… that’s not how that works.”
