You can eat the food and drink the beverages in the store.
Two years ago, I applied for a position at one of the company's stores in Taichung. Despite this being labor-intensive work, it was still subject to an accountability-based work system, with no overtime pay for extra hours worked and no labor or health insurance. There were only six days off per month, and the salary for a full-time position was NT$22,000 (despite having two years of food and beverage work experience). Most outrageous of all, delivery was considered the responsibility of the male colleagues only (isn't gender equality something that is constantly discussed in Taiwanese workplaces?). I felt these were extremely poor working conditions.
