Oh yeah, our DQ always held the Blizzards upside down.
Ours used to also sell off in the freezer (where they sold the take home items like Buster Bars ,Dilly Bars, ice cream sandwiches) - bags of 'mistakes' - so if they screwed up an order, they would still sell it off. They weren't labelled so you never knew what you got, but oh, it was fun!
Apparently there is no cherry dip anymore at DQ? I'm gutted if that's the case, because I always loved a cherry dipped cone!
