Shift Drink Eddie Kim, Mathew Ramsey Welcome to Shift Drink! Long hours on sore feet and wearied coworkers cramped side-by-side in the pursuit of perfection is typical in the service industry. But it isn’t until the final diner has gone and the last tab is closed; when there are no more pots to scrub or glasses to polish; that’s when the first shift drinks are poured and the stories start to flow. Every week, Eddie Kim and Mathew Ramsey will share a shift drink and swap war stories from behind the line with chefs, bartenders, bakers, brewers, and anyone who touches this all-encompassing industry. Un-edited, no-holds-bar, and personal, these brief moments bleed into life stories, past and future aspirations, philosophy, life lessons and every shot in between. This show records and broadcasts LIVE on Full Service Radio from the lobby of the LINE DC in Adams Morgan, Washington DC. Explicit
