No Such Thing as a Stupid Question?

I believe that that saying should be re-evaluated. The other day in drivethru, this lady comes through and asks, "Is there any ice cream in the Frappes?" We think Oooooooooookay...sort of a valid question. Some of us thought they were. My friend gets on the headset and says "No, they're made with blended ice and Carmel or mocha flavoring." The lady's next question? "Is there any ice cream in the milkshakes?" ...um, yes? So then I get on the headset and say, "Yes ma'am, our milkshakes are made with ice cream." And then she orders two apple pies and a Coke! As if that weren't a stupid enough question (I'm sorry, but how do you not know that there is ice cream in a milkshake?), she doesn't even want a milkshake or a Frappe, she wants two pies and a POP!
That, my friend, was a stupid question.
