DQ marketing is different up here. Most of them are open from Mid-April to Late-October. That creates a craving that comes with the excitement of spring. It is a treat to go for a DQ ice cream in the heat of summer, but most of us never eat their burgers. The few DQ's I've seen with seating areas never seem to last long.
I liked your list, aftr, 16-21 easily apply to me.
When I was a kid, about 1970, they’d never heard of a milk shake at DQs in Minnesota. My grandfather had cancer and couldn’t eat a hamburger so had to have something through a straw. We had to teach them how to make shakes and they just shook their heads like we were crazy. To think that’s their mainstay today is weird.
