It's all bullshit upstairs! There are bar teachers in bars, cafes, tea rooms, spas, water bars and pharmacies. As the name implies, it means the owner of the bar. Bar teachers are higher than bar students in both professional titles and positions, so they need to guide the work of bar students to some extent! They need to be very familiar with the workflow in the store and have some work experience! For example, you need to be very familiar with the recipes in the kitchen and the specific methods of each dish, and be familiar with the etiquette and coffee making process of the coffee shop. Familiar with skilled coffee and wine preparation, fashion milkshake, Buffy, bubble tea, herbal tea, fruit tea and art fruit bowl tea art! Some also require bar teachers to have certain performance skills and abilities!
