have policy to those workers like them who handled many customers,using mobile fone must be prohibited and those who caught will have penalty,why allowing workers to use fone during working hours?It will distract and disturb the work thus if any problems occur because of that chatting or what ever they talk on the fone,the pressure or anger burst out to the customer,then the customer may complain of the wrong behavior of the cashier...

I also experienced this kind of workers,sometimes i told them to be attentive to their job and customers in our dialect in a polite way..somehow they feel embarrass but its good to enlighten their mind...
