Waitrose and John Lewis are offering free hot drinks to on-duty police officers in a bid to deter shoplifters.
John Lewis Partnership, which owns both brands, has written to the Police Federation to say officers can make the most of the offer – as long as they bring a reusable cup.
Its head of security said that even just having a police car parked outside might deter would-be thieves.
It comes as other shops have reported soaring levels of retail crime.
In Waitrose, police officers and community support officers will be able to get drinks from the in-store coffee machines.
The supermarket used to have a generous offer of free teas and coffees for all shoppers who had a loyalty card.
