Mitchells & Butlers has been accused of using "guerrilla" marketing tactics after one of its pubs offered to accept discount vouchers from a rival outlet. The Willow Tree in Torquay, Devon, which is part of M&B's Innkeeper Fayre estate, put up a huge banner saying it would accept special offers advertised in the local paper for the nearby Brewers Fayre. They include two meals for the price of one. The manager of the Brewers Fayre, run by Whitbread, has accused the Willow Tree of "living off the back" of the Inn-keeper Fayre brand and "nicking his customers". M&B insists there is nothing wrong with its actions and has admitted the policy is used in other pubs to drive up custom. James Crowther, manager of the Brewers Fayre, said: "A lot of people think the Willow Tree is a Brewer's Fayre, but it's not. "They are living off the back of our advertising and national campaigns, which we are paying for. It's like walking into Tesco and saying they will accept Sainsbury's vouchers." A spokesman for M&B said: "It's not a completely isolated incident, we have done this before. At the end of the day this gives customers more choice.
