Starbucks says it is reversing rules for its cafes in North America that allowed people to use its facilities even if they hadn’t purchased anything.

The changes, set to take effect Jan. 27, represent a reversal from a policy introduced six years ago that allowed people to linger in Starbucks stores and use their restrooms without purchasing anything.

The move is part of the “Back to Starbucks” strategy – a plan announced by the company’s new boss as he tries to address declining sales.

The world’s largest coffee chain says its new code of conduct – which also addresses harassment and bans smoking and alcohol outside of drinks – aims to make its stores more welcoming.

“Implementing a coffeehouse code of conduct… is a practical step that helps us prioritize our paying customers who want to sit and enjoy in our cafes,” a Starbucks spokesperson told BBC News.

“These updates are part of a broader series of changes we are making to improve the cafe experience as we work to return to Starbucks.”

The company said the new rules will be posted in every store and staff will be instructed to ask anyone who violates the code of conduct to leave. This also includes allowing employees to call the police if necessary.

In 2018, Starbucks decided to provide free access to its coffee shops and restrooms following the controversial arrest of two men at one of its cafes in Philadelphia.

Other changes to be rolled out later this month include offering a free hot coffee or iced coffee refill for customers who purchase a drink to consume on-site.

Starbucks has been trying to boost flagging sales as it struggles with the backlash over price hikes and boycotts sparked by the Israel-Gaza war.

It was Brian Niccol, who previously ran the Mexican grocery chain Chipotle introduced at Starbucks last year to help get the business back on track.

Mr. Niccol has tried to improve the customer experience at Starbucks cafes Revising its menus and cafes.

Starbucks said the policy change applies only to North America and not to its stores in the United Kingdom.

However, it has not yet responded to requests for comment on the details of its UK policy.
