Sheila Dillon heads out on the highway to investigate the world of food at motorway service stations. Historically they have been a place viewed as a functional stop-off for a "tea and a pee" and often maligned for the quality of their food. Motorway services enthusiast Dr David Lawrence from Kingston University talks through a short history of the Great British service station from Watford Gap and Newport Pagnell in 1959 through to present day.

AA President Edmund King briefs Sheila on how his membership views motorway service food and Robin Markwell reports on the opinions of lorry drivers from Chippenham Pit Stop on the M4 in Wiltshire where more healthy eating options are now appearing on the menu. Dan Sutton from Roadchef - one of the largest motorway service operators - also gives his thoughts on what the British motorist is looking for when wanting to be fed on the motorway and argues that familiarity of brands is key.

Sheila takes a trip to Tebay Services on the M6 in Cumbria to understand a different way of providing motorway service food. She meets the Dunnings family who have since opened services at Gloucester, Cairns Lodge in Lanarkshire and will soon open another at Tatton in Cheshire. Their ethos includes an emphasis on locally sourced, homecooked food. Sheila meets with their coffee and bread suppliers as well as touring their farm to understand how service areas might also be an engine for the local economy.
