Ignorance...

I had no idea that a margarita had alcohol in it. I work as a caterer for one of my jobs, and asked the bartender, if the drink he was giving to me was a virgin margarita. He laughed and said yes, but to drink it quickly before this anal lady i work with saw me. My friend took one too, so I thought it was a safe drink. As I am rushing out the doors to the back, I tell me friend to quickly drink it because Mary would be here soon, and I took a sip, then I heard the word "Don't drink, that has alcohol in it" by my friend. The moment she said it, i had already swallowed once, was bending over a trash can spitting out the rest, and trying to get the rest up. It felt like my throat was on fire.
Moral of the story:
Don't trust a bartender...
