BUZZER for customers

how to improve customers satisfaction when waiting for the order to be done? here is one of the idea that i had seen in majority Cafes in Korea that improve the customers satisfaction.

Introducing the "BUZZER"

Generally, a buzzer or beeper is an audio signalling device, which may be mechanical, electromagnetically or piezoelectric. Typical uses of buzzers and beepers include alarm devices, timers and confirmation of user input such as a mouse click or keystroke.

Korean Cafe used this buzzer as a tool to tell their customers that orders is there. customers will wait at tables in the cafe and have a chit chat while waiting for the orders. this had improve the customers satisfaction while ordering because they did not need to stand at the counter anymore to wait for the orders. 

Workers also will feel easy because they didn't have to bring the drinks to customers because it is self service. customers will have to come and take their on drinks once the buzzer ring.

I think this is a very good idea or strategy that Korean Cafes had implemented in their business. it improve customers satisfaction and also smooth en workers duty.
