COLORADO SPRINGS — I try to avoid the word “ironic” because it is so often misused, but when a shouting match breaks out during an etiquette class, I’m going to say it fits. The “Minding Your Ps and Qs” class was just wrapping up in the Broadmoor’s stately Penrose Room when one of fathers called out another about his sons “rude behavior” — which included talking over and interrupting the instructor all the while bouncing up and down on the upholstered gold-framed chairs. Of course that instructor, a patient young man named Travis Molinari who serves as sommelier and supervisor in the Penrose Room, wasn’t the least ruffled as he continued with his napkin folding demonstration. And though I crossed paths with the other class members repeatedly throughout our stay, the troublemakers were never to be seen again.
