Back in high school I worked at an ice cream shop. We had a bunch of different toppings available for sundaes including butterscotch and caramel. The interesting part was that those two flavors were actually the same thing. It even said butterscotch/caramel on the package. Nobody ever complained. If they were expecting caramel, they tasted caramel. If they expected butterscotch, they tasted butterscotch.
