 Oh my God, she's dumping alcohol into her coffee. And she looks very pleased with herself while she's doing it. Anyway, this is another popular invention. It was these canes, and you twist open the cane. There's a long glass vial inside you can fill with liquor and, of course, just screw it out and pour it into whatever. There are reproductions of this cane on eBay. I happen to own one of them.
