• Starbucks now allows customers to bring their own cups for drive-thru and mobile orders.
• It's part of a companywide effort to reduce waste by half by 2030.
• But some baristas are worried about how the reusable cup program will actually work.

Starbucks is now letting people bring their own cups for mobile and drive-thru orders — and some baristas say they're worried about how it will work.

Starbucks had already allowed customers to bring their cups to the counter for in-person orders. This extension of the program is part of a push to cut the company's waste in half by 2030.
