Drinks don't have to be exotic to be vile.
Worst I ever had was Diet Pepsi and cheap vodka. Finals week, junior year in college, I discovered that I had not received the notice stating that time had been changed for one of my Econ exams and I had missed the exam. I stopped by a friend's room to vent and she offered me a drink. Gak!

Not a Pepsi person to start with, and add cheap vodka - haven't touched either since then.
The good news is the proof let me make up the exam because she knew me well enough to know I'd never miss it on purpose.
