Today I had a customer pull up to DT and ask for a "Caramel macchiato frappuccino."
Once customers like that get to the window I tend to laugh with them about it because I find it's a great chance to educate them without sounding pretentious or confrontational. I explained to him that a caramel macchiato frappuccino doesn't exist and would actually be impossible, because the blending would negate the entire effect and turn it into a standard caramel frap.
My supervisor, who overheard this, jumped in to explain that it would be possible. We'd just throw the espresso shots on top of the otherwise-completed frap like always, apparently.
I don't know about you guys, but that sounds pretty vile to me. But, hey, there you go.
