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.

The free refills will be served in coffee mugs, glasses, or a clean personal cup brought from home and are only available on the same visit at one store. The refills excludes Cold Brew and Nitro Cold Brew, Iced Tea Lemonade, flavored Iced Tea and Starbucks Refreshers® base. Initial purchase must be made in a reusable cup or “for-here” serveware.

According to Starbucks' new code of conduct, nonpaying customers will no longer be able to use the coffee shop's restrooms.
