Spilled a Secret While Mixing Drinks

So here's the deal, I'm pretty good at keeping secrets. The kind of bartender people come to when they need someone to listen and keep their stuff close to the chest. But last night, things got really wild with everyone ordering round after round, and I just lost it. I was mixing drinks like mad, and suddenly this guy spills his guts about being in love with his best friend's sister. Not even a crush; he’s out of his mind over her. I didn't mean to, but as I handed him his drink back, I blurted out something like, 'If you ask me, you should just go for it!' Total mistake, turns out everyone else at the table heard me too. It was so embarrassing! Of course, people think I'm great at giving advice now, which is hilarious because honestly, what do I know about love? So here's my question: am I totally nuts to not have kept this quiet, or does every bartender have a moment like this?
