After work, I traveled with my fiance to Columbia Maryland to get dinner. I decided to order a margarita after the Waitress suggested that the margaritas were her favorite. The drink arrived after about 18 minutes. I really like this particular beverage so was excited to taste....I immediately sensed something strange. I mentioned to this to my fiance and then to the waitress. The waitress gestured in an unaccommodating fashion and made a strange face. She asked what was wrong but was very rude. As I begin to feel sick (water mouth, dizzy, etc.). As she was going to get alternative drink, my fiance stopped her. During this situation, I ran to the rest to throw up about times and it smelled JUST like the drink (sour). I was sooo sick. I was mentally upset me because I had no idea what I had just consumed. The manager finally came over after he was ushered over. He wasn't very helpful; suggested I had a "bug" and brought over some sour mix to "proof" that it was freshly made. My guess is that was contaminated. I was sick for two days and still get that watery mouth sensation if I drink or eat. I don't know what to do. I will say that I noticed many partially consumed consumed margarita on tables that had been previously occupied. I should have taken a picture but was dizzy and upset. The manager said he'd call to check....never did.
