Retailers selling fresh American hot dogs have increased weekly food to go sales by as much as £200.

Peter Lamb, of Lamb’s Larder in East Sussex, sells ten a day. He told RN: “We put the machine in just over a month ago and we sell 70 per week on average, at £2.99 each.

“Having the machine at the till helps because customers can smell the hot dogs and it encourages impulse buying.”

Chris Herring, of Londis in Torquay, added: “They’re one of our bestsellers. We sell 30 at £1.99 per week. Customers prefer them on the go.”
