Just Say No

Why oh why don't I ever say, "No potatoes, please" to the cook at the Atrium Cafe' in my office? Whenever I order an omlet, it comes with potatoes. They're not bad or anything, but they're nertno good (no onions or anything cooked with them, they've got a weird grill flavor, I'm not a fan). But if they're on my plate, I can't help eating them. I do not want the potatoes. The toast is plenty. Yet I cannot bring myself to ask for no potatoes. What's the deal?
