What certificate do I need to work part-time in a coffee shop?

The first is the health certificate. Whether you are a waiter or a barista, a health certificate for the catering industry is necessary.

Two, domestic barista qualification certificate or international barista qualification certificate.

The international barista qualification certificate has a high gold content, such as City&Guilds, which can be employed as a barista whether it is developed abroad or in the ubiquitous cafes in China (Starbucks, Ruixing).
