If an MC accepts an open drink at a club one more time, I’m calling the police myself 🍸🚨

The MC goes to a bar or a high-society party. A suspicious stranger with shifty eyes hands him a neon glowing drink and says, "Drink this, it's just grape juice." And the MC downs it like water! Three panels later, his body is on fire, his vision is spinning, and the ML has to swoop in for an "emergency rescue." Has anyone in this universe ever heard of basic cup safety?! What is the most obvious, ridiculous trap drink an MC walked right into?
