I've actually gone to Starbucks and tried to order a "car-mel" frapicino. When she had no idea what I was talking about. But once I changed my order to a "care-a-mel" frapicino there was no language barrier.
And according to the boy there's an old Snickers commericial where Shaq argues with a kid on the right way to say caramel. We all know that the "right" way to say it is the way I do, as "car-mel." But how do you say caramel? If there some other pronuciation that I'm not even aware of?
