It is Red Cup season! Under halogen lights, red metal tumblers gleam and pinken plastic to-go mugs. Swirled teacups shine like candy canes. Behind the café counter, whipped-cream ski hills top the menu of seasonal drinks with a flurry of diamonds and snowflakes. In sizes tall, grande, and venti, towers of patterned coffee cups are plucked by red-aproned baristas, like ornaments off a tree.
