You know, I was sitting in a Wendy's the other day sorta thinking about this Double Down thing and chuckling to myself when it dawned on me...
You could buy like 2 of those deluxe chicken sandwiches that Wendy's has (that's what I was eating), toss the bread, turn one upside-down, and stick em together. They already have bacon and cheese. Voila, instant Double Down for only $3.00 tops. But you might look weird doing it in a place that doesn't have a sandwich like that. So maybe start your order by asking if they have a sandwich like that, and then move on to the sandwich creations from there. lol
