poor customer service

Pnp Promenade has 30 cashier tills to service customers. Yet they are not being utilised. The checkout lines are running down into the shopping illes and yet management only utilises 10. I am dumb struck by the poor use of resources. It is very poor resource management. And this is one of PnP major revenue stores and yet the level of service rendered to the customers who make them one of PnP top grossing stores. Still treats their customers this way. Its appalling and things need to change.
