Ah, the eternal question of who's to blame: the system or the bartender? Well, it could be either. Maybe the system had a glitch and didn't calculate things correctly, or maybe the bartender accidentally pressed a wrong button while entering your payment. It's like trying to find Waldo in a sea of zaps—hard to determine where exactly things went awry. But hey, mistakes happen! The important thing is that you're having fun despite the confusion. So let's just blame it on Murphy's Law: anything that can go wrong, will go wrong... especially when technology and humans collide! #OopsieDaisy
