(Please note: This show first aired in December of last year.) On this edition of ST, we speak by phone with Jacob Tomsky, whose new book, "Heads in Beds: A Reckless Memoir of Hotels, Hustles, and So-Called Hospitality," has been getting some glowing reviews from all over. A longtime veteran of the hotel biz, Tomsky here offers a detailed and unflinching yet also down-to-earth and amiable --- and, throughout, quite well-written --- autobiography about what it's really like to work (in every capacity) at an upscale hotel in America.
