Changes arrive at Starbucks US. cafés on Monday, including a new code of conduct, free refills and the return of condiment bars. Why it matters: The coffee giant has been trying to reverse a decline in foot traffic and go back to its roots under a plan Starbucks CEO Brian Niccol outlined in September.

Starbucks is bringing back free refills and a condiment station, but there are few rules to be able to use these services.

No disposable or plastic vessels will be able to get the free refills. Additionally, if you purchase a cold brew, latte, Starbucks Refresher, Iced Tea Lemonade and many other drinks, you won’t be able to get the same drink for your free refill.

Starbucks' policy requiring purchases in order to use restrooms or hang out at the coffee shops began today. The chain's free refills era also starts.

Starbucks customers in the U.S. and Canada will notice some changes when they visit a Starbucks location on Monday, including the re-introduction of condiment bars.

The coffee chain giant now requires purchases to hang out or use the restroom. Customers can get free refills on drinks.

Starting today, you may start to notice a few big changes at your local Starbucks. As a part of their Back to Starbucks initiative, the coffee chain is implementing some exciting newness to their in-store ordering process.
