Recently, a sports supplement called "pre-workout" has been hailed as a "magic weapon for PE exams" ahead of the high school entrance physical education test, and is sought after by many parents. However, media reports have successively reported cases where students experienced rapid heartbeat, vomiting, and even needed emergency gastric lavage after drinking it. The reason is that such products generally contain high levels of caffeine, some as high as 500 milligrams, far exceeding the safe threshold. Professional fitness trainers and doctors both remind that minors blindly using such high-intensity supplements is extremely risky. If there is a need for a pick-me-up, it is better to choose a cup of coffee. [more…]

The Starbucks secret menu once led baristas to learn how to make over 170,000 customized drinks, but the extremes of personalized orders are sparking controversy. An American barista was fired for exposing a customer's 13-request order on social media, then apologized in person and settled the matter.

Starbucks China launched three new products for the New Year: Belgian Dark Chocolate Latte, Dark Chocolate Black Tea Latte, and Coconut White Chocolate Latte, featuring a combination of 57% Belgian-origin dark chocolate and oat milk, attracting attention from many chocolate lovers. However, behind the hot sales of the new products, baristas have been complaining on social media: the chocolate sauce used this time is unusually thick, prone to clumping and hardening in winter, extremely difficult to operate with metal squeeze pumps, making consecutive cup production feel like weightlifting, and it easily drips and stains the bar and clothes. What's even more frustrating for workers is that there are reports that this series may shift from a seasonal limited edition to a permanent offering. [more…]

In the extraction parameters of espresso, pressure is often regarded as a variable that is not easy to adjust but has far-reaching effects.

Recently, a post about 1 Dian Dian's navy salt salted milk green tea charging an extra 2 yuan for added salt sparked widespread discussion on social media. Some customers, following online guides, asked for extra salt, only to be told that one pump of salt costs 2 yuan, which was far from their expectations. Subsequently, 1 Dian Dian employees and official customer service explained that the "salt" is actually a relatively expensive navy salt rock sugar flavor syrup, and according to company policy, additional additions require payment. Although the store has apologized for the incorrect price quote, netizens have derived a new question: since adding sugar costs money, should customers who order less sugar or no sugar also get a refund for the corresponding syrup price difference? This debate about the pricing logic of tea drinks quickly became a topic of interest for coffee and tea enthusiasts. [more…]
