Besides refreshing the mind and waking you up, coffee can also promote intestinal peristalsis, which unexpectedly makes the restroom experience an important standard for judging whether a coffee shop is comfortable. Recently, a netizen from Shandong posted on social media, reviewing some of the coffee shops they had visited from the perspective of the restroom, with a unique angle and rich details. Cleanliness and hygiene, along with smooth flushing, are the basics, while spaciousness and ventilation, pleasant aromas, and the provision of disposable toilet seat covers, wet wipes, sanitary pads, and hand cream become bonus points. A layout with dry-wet separation and a reasonable flow also greatly increases favorability.

Those shops with complete facilities not only meet physiological needs, but also win repeat customers and reputation through detailed service.

Although drip bag coffee and instant coffee are both convenient and quick, they are worlds apart in terms of production process and drinking experience.

After the Luckin Yuzu C series returned, it quickly became popular, and many people on social platforms have hailed it as a "fat-flushing miracle," with claims even circulating that "one cup can make you lose two jin." However, actual test data show that although a single cup of the Yuzu C series contains about 105 to 150 calories, blood sugar rises fairly quickly after drinking it, and the blood sugar increase of Yuzu C Iced Tea can reach 5.1 half an hour after a meal.
