Introduction:When you order a hot Americano and add oat milk for an extra charge, have you ever considered that this seemingly small option might come with hidden traps involving both price and portion size? Recently, Peet’s Coffee stirred consumer skepticism with its “add oat milk for ¥2” option — inconsistencies between what the store said and what customer service claimed left customers confused about the actual drink portion they received and how much they were paying. This article delves into the full story of the incident, explores common pricing practices among major chains and independent coffee shops for adding milk to an Americano, and offers practical ordering tips to help you avoid similar disputes and enjoy your coffee experience wisely.
Recently, a consumer dispute regarding Peet’s Coffee’s “Americano with oat milk” option sparked widespread discussion on social media. A customer ordered a hot Americano and selected the “add oat milk for ¥2” option available on the online platform. However, upon receiving the drink, they found that the amount of oat milk was noticeably small and the color was lighter than expected. After inquiring at the store, they learned that the so-called “add oat milk for ¥2” actually only included about 30 milliliters. To increase it to 50 milliliters, an additional ¥2 had to be paid, and the customer had to specifically note “only 50ml,” otherwise the staff would add the system’s default amount.
Even more confusingly, when the same customer contacted Peet’s official WeChat mini-program customer service for clarification, they received a completely different response. The customer service representative stated that selecting the “add oat milk for ¥2” option should include approximately 50 milliliters of oat milk, and made no mention of any additional fees or tiered additions. This contradiction in information led the customer to question the brand’s consistency and transparency.
In fact, such disputes are not isolated incidents. Many coffee enthusiasts enjoy adding a small amount of milk to their black coffee to mellow the flavor or adjust the taste. Whether it’s international chains like Starbucks, COSTA, %Arabica, or independent coffee shops on the street, most offer an “Americano with milk” option — but the pricing standards for adding milk vary significantly from place to place.
According to industry insiders, some coffee shops provide free milk or oat milk within a certain volume limit, charging extra only when the basic amount is exceeded; some only offer free milk, charging for more expensive oat milk regardless; while others do not charge any extra fees no matter how much milk is added. Such a diverse and inconsistent set of rules often leaves customers unsure of what to expect when placing an order.

Returning to the Peet’s case, the customer emphasized that she had no issue with paying an additional fee, but was confused by the two completely different explanations given by the store and the official customer service. She believes that since the brand offers a milk-addition service, there should be unified product standards and clear pricing rules, rather than leaving customers to guess how much they’ll actually get or having to ask proactively to find out.
After repeatedly providing feedback to the company, the customer finally received a response. A regional manager from Peet’s personally reached out to apologize for the unpleasant experience and pledged to carry out comprehensive improvements across all national stores and online ordering platforms — including the official mini-program and third-party delivery services. The focus of the rectification is toclearly display the actual portion size and corresponding price for each add-on optionon the ordering interface, preventing similar misunderstandings from happening again.
Currently, these rectifications have been fully implemented. On all ordering platforms, customers can now clearly see the actual amount of oat milk added to an “Americano with oat milk” (for example, around 50 milliliters) and the corresponding cost, eliminating worries about paying more due to lack of transparency or receiving a drink that doesn’t meet expectations.

This incident reminds us that even when patronizing well-known chain brands, it’s important to pay attention to the details of your order and the descriptions of optional add-ons. It is recommended that when choosing a milk-addition service, customers actively confirm the amount being added and the associated cost, or check the detailed descriptions on the online ordering page in advance, to ensure they understand the actual contents and pricing structure of the drink they’re ordering. In doing so, not only can misunderstandings be avoided, but you can also enjoy every cup of coffee more happily.
