The Coffee Connoisseur at Work

Hey there, fellow night owls! I'm that guy who's never seen the sun rise (except when I’m driving back home after my shift). You know the type, I’ve got so much energy it feels like caffeine is flowing through my veins instead of blood. But here’s a confession: I don’t just drink coffee, I study it. There are days when I brew at least three different types and carefully taste each cup to see which gives me the best balance between taste and that all-important kick. My coworkers joke that they should take turns bringing in samples for my 'tastings,' but honestly, I'm kind of proud of how much I know about caffeine these days. So, here’s where it gets interesting: sometimes when I’m feeling extra bold (or maybe just really wired), I might sneak a cup from the office coffee machine and leave behind an old cup that looks like what I actually drank. The next day, everyone's talking about how weird my coffee was last night, and they can't figure out why their own morning brew tastes different too! Is this normal? Do other people have fun with this kind of prank or is it just me who gets a kick out of being the caffeine king of the night shift? Let me know if you ever tried anything like this!
