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.

These customers will be able to enjoy free refills on hot brewed or iced coffee, or hot or iced tea during their visit. Starbucks says folks must have their first beverage served in a ceramic mug, glass or personal cup — no disposable vessels — to receive free refills.

Starbucks fans can now get free refills for some drinks — but not all. The coffee chain is also bringing back its self-serve milk and sweeteners bar.
