Response from Starbucks

Dear Valued Customer,

Thank you very much for your enquiry.

Our barista is required to ask customers if they prefer their coffee " for here (coffee mug) " or " to go (paper cup) ". Thank you very much for your interest in Starbucks.

Yours
Sincerely,
May Tse
Operations Manager

The baristas are required to ask. If they don't, let's tell them.
