My friend had a cafe in the Houston suburbs once ages ago. He splurged for these dank cardboard cups that didn't need the little circle of extra cardboard to keep from burning your hand - he didn't like those cause he'd see them on the ground everywhere and he believed they made people more likely to accidentally drop their cups. Anyway, something like 90% of people would ask where the little cardboard sleeves were in his shop or through the drive through, even if he explained he got good cups that don't require it. It just wasn't a concept for people - they needed their sleeves or they'd burn their fingers, of course!
