In the recent time, POS Online has visited our client’s stores to learn the way they operate their business. And we were amazed at the operation of one of our customers. Only 2 staff have served more than 20 customers at the 800 square meters ground. However, the most impressive part is that the customers did not have to wait for a long time to get their drinks. Both staffs worked extremely efficiently so they still had time to rest after serving. After several hours watching the store operation, we finally realized some of its successful service secrets.
