Posters warning people not to urinate against walls and defecate in bushes have been put up at Watford Gap services in Northamptonshire to try to stop people using the picnic area as a toilet.
Northamptonshire Police has created the poster, which shows images of both activities crossed through in red, in an attempt to encourage people to use the facilities inside the building.
The BBC reported that 20 posters have been put up at the northbound service area designed to be clear to “people from across the world”.
A spokesman for Northamptonshire Police said: “We work closely with the management at Watford Gap and it came to our attention that bushes by a picnic area and a lorry park at the service station were regularly being used by people as a toilet.
“To tackle the problem, we created a poster which aims to encourage people to use the facilities inside the service station building.
“As people from across the world use the service station, we designed the signs to be as easy to understand as possible.”
A spokesman for Roadchef, the company which runs the Watford Gap services, said there had been “a very small number of incidents” of people using the outside area as a toilet.
The spokesman said: “We do not condone people using our site inappropriately in any way, and monitor car parks at all of our sites to ensure every customer receives a good experience when using our facilities.”
