I've got it from a famous chain that everyone knows; it's a typical cheap place for sandwiches, but I am not going to name it because this post can get deleted if I did so. It is entertaining just to observe their customer service there... real quality place! Though believe me, I was quite pleased to stumble upon such a rare moment in food-consumption history: Witnessing a hair-looking thing sticking out of the cheese doesn't happen every day, and really makes my day more special! I love mistakes like that, and I kind of thrive on them. See, if it wasn't for that, you wouldn't have been able to enjoy this pleasant-looking photo. On the picture, it looks like a leg of a cockroach, but when I observed it up close and from all sides, I don't think it was a roach; it looked more like some kind of a thin streak of fabric, not hair, because hairs don't fold in that way. Anyway... enjoy!
