This has been bugging me every time I go to my local sandwich shop. It's part of a triptych that begins with "Oooh...!" and ends with "Mmmm...!"
I'm sure they meant "Ahhh...!" but what they ended up with was an exclamation of shock and fear. Because the photo depicts my favorite sandwich, I always end up sitting across from it thinking, "What's so scary about the #4 on white with standard toppings?"
