Peanut Butter and Swiss Cheese

A lady walks in and immediately shouts: "I need a toasted bagel with peanut butter and swiss cheese!" I am initially shocked by this since I didn't even have time to ask her what she wanted. Then upon seeing my face she says "I know it sounds weird, but it's delicious." And then things go downhill from there when I inform her that we don't have either of those ingredients, since I am a coffee shop, not a sandwich shop. Oops
