A chain of pubs is asking drinkers to curb their language and banned customers from swearing.

Samuel Smith, which has dozens of watering holes through the capital, has instructed staff to crack down on potty-mouth language.

Among the pubs which will be affected in west London are the Earl of Lonsdale in Notting Hill , The Town Wharf in Isleworth , The Windsor Castle in Victoria, The Eagle in Warwick Avenue and John Snow in Soho.

Are they taking the p**s?

A member of staff at the Earl of Lonsdale confirmed the zero-tolerence approach, but was not sure how the rule would implemented.

They said: “It’s all Samuel Smith pubs, my manager told me this week.

“I don’t think it will go down very well because some of our drinkers swear a lot.”

Gazette Live reports some of pubs have also displayed a memo which was sent to “all pub managers” from area manager, and Samuel Smith’s Old Brewery owner, Humphrey Smith.

Dated April 12 this year, the full policy says: “Please note that with immediate effect, the company is introducing a zero tolerance policy against swearing in all of its pubs.

“As manager(s) of our pubs, you are responsible for ensuring that they are run in a proper and orderly manner and this includes preventing the use of bad language.

“If customers, and staff alike, swear on the premises then you must ask them to refrain from using bad language.

“If, after asking a customer and/or member(s) of staff to refrain from using bad language they continue to do so, then you have the authority to take reasonable steps to ensure that they comply with the policy i.e. you must refuse to serve them.”

The manager of a Samuel Smith’s pub in Teesside said: “It’s the owner of the brewery’s decision, it’s all started from the brewery - all we can do is try our best.”

Asked if the policy could see some customers barred, he added: “We’ve been told to refuse service to people using bad language, so basically, yes.”
