So when I passed a Burger King yesterday while traveling, I decided to take advantage of the BOGO Original Chicken Sandwich offer in the app.\n\nMy first surprise was when I took a bite of it. It looked like a chicken sandwich - bun, chicken, lettuce and tomato - but the whole thing had this pasty mouth-feel. I couldn't tell where the bread stopped and the meat (?) began. It was like eating a simulated sandwich made out of Play-Dough.\n\nThen the taste hit me - a combination of acrid rancid oil and chemical fake-chicken taste. I kept eating and tried to push through it. I made it halfway through the second sandwich before I threw the rest out. (And I never throw *anything* out.)\n\nBut that one-two taste combination didn't go away. It coated my throat. It stayed on my tongue. My drink wouldn't wash it away. When I got home, I ate more food but the taste was still there. It was at the back of my throat. It was in my breath. I could not get away from it.\n\nThe next morning, I woke up with a very rumbly stomach. I kept burping up that rancid/chemical-fake-chicken taste, now mixed with stomach bile. Then it started coming out both ends. I'll spare you the details, but the sounds and smells were just awful. Somehow the chemical-fake-chicken component...",
